a. Calculating the Percentage of Salary Remaining After Charity

The initial question focuses on determining the percentage of Ken's salary that remains after he makes a charitable donation. Ken's salary is $1200, and he donates 20% of this amount to charity. To calculate the remaining percentage, we first need to find the amount he donated and then subtract that from his total salary. This step-by-step process will help us understand the impact of his donation on his overall financial situation. Understanding these percentages is critical for anyone looking to manage their finances effectively. By knowing how much of your income is allocated to various expenses and savings, you can make informed decisions about your spending habits and financial goals. In Ken's case, understanding the percentage of his salary that remains after his donation provides a clear picture of his financial health and allows him to plan for future expenses and investments. Furthermore, this calculation highlights the importance of budgeting and financial planning, which are essential skills for individuals and households alike. By taking the time to analyze your income and expenses, you can gain valuable insights into your financial situation and make informed decisions that align with your financial goals. Ultimately, mastering these fundamental financial calculations can empower you to take control of your finances and achieve long-term financial success.

Step 1: Calculate the Amount Donated to Charity

Ken donates 20% of his $1200 salary to charity. To find this amount, we multiply his salary by the donation percentage:

Amount donated = 0.20 * $1200 = $240

This calculation shows that Ken donated $240 to charity. This act of generosity not only benefits the charity but also reflects Ken's values and priorities. Donating to charitable causes is a meaningful way to support organizations that are making a positive impact in the world. Understanding the impact of donations is also important for personal financial planning. While charitable giving is commendable, it's crucial to balance generosity with your own financial needs and goals. By carefully budgeting your donations, you can ensure that you are contributing to causes you care about without compromising your financial stability. In Ken's case, donating $240 represents a significant portion of his income, but it is essential to consider this in the context of his overall financial situation. This includes assessing his other expenses, savings goals, and long-term financial plans. By taking a holistic view of his finances, Ken can make informed decisions about his charitable giving and ensure that it aligns with his broader financial objectives.

Step 2: Calculate the Remaining Salary After Donation

Now, we subtract the donation amount from his total salary:

Remaining salary = $1200 - $240 = $960

After donating to charity, Ken has $960 remaining. This amount represents the funds available to him for other expenses and savings. Understanding the remaining salary after donations is crucial for budgeting and financial planning. It allows Ken to assess his available resources and allocate them effectively to meet his needs and achieve his financial goals. Effective budgeting involves prioritizing expenses, setting financial goals, and tracking income and spending. By creating a budget, Ken can ensure that his spending aligns with his priorities and that he is making progress towards his financial objectives. In addition to budgeting, it's also essential to consider savings goals. Saving a portion of your income is crucial for building a financial safety net, preparing for unexpected expenses, and achieving long-term financial goals such as retirement. By setting savings goals and tracking progress towards them, Ken can build a solid financial foundation and secure his future. Ultimately, managing your remaining salary effectively requires careful planning, budgeting, and a commitment to achieving your financial goals.

Step 3: Calculate the Percentage of Salary Remaining

To find the percentage of salary remaining, we divide the remaining salary by the original salary and multiply by 100:

Percentage remaining = ($960 / $1200) * 100 = 80%

Therefore, 80% of Ken's salary is left after the charitable donation. This percentage provides a clear indication of the financial impact of Ken's donation. Understanding the percentage of salary remaining is essential for financial planning and budgeting. It allows Ken to assess the portion of his income that is available for other expenses and savings. Financial planning involves setting financial goals, developing strategies to achieve those goals, and monitoring progress over time. By understanding the percentage of salary remaining, Ken can make informed decisions about how to allocate his resources effectively. This includes prioritizing expenses, setting savings goals, and planning for long-term financial needs such as retirement. In addition to financial planning, budgeting is a crucial tool for managing your finances effectively. By creating a budget, Ken can track his income and expenses, identify areas where he can save money, and ensure that his spending aligns with his priorities. Ultimately, understanding the percentage of salary remaining is a key component of effective financial management.

b. Determining Ken's Original Amount Given Remaining Funds

The second question presents a different scenario: Ken has $1200 left after donating to charity and spending 50% of the remaining amount. We need to determine his original amount. This problem requires us to work backward from the final amount to the initial amount. Working backward is a common problem-solving technique in mathematics and is particularly useful in financial calculations. By retracing the steps and reversing the operations, we can uncover the initial value. In this case, we will reverse the process of spending and donating to find Ken's original amount. This exercise demonstrates the importance of understanding the inverse relationship between mathematical operations. For example, addition and subtraction are inverse operations, as are multiplication and division. By applying these concepts, we can solve complex problems by breaking them down into smaller, more manageable steps. This approach not only makes the problem easier to solve but also enhances our understanding of the underlying mathematical principles. Ultimately, mastering these techniques can improve our problem-solving skills and enable us to tackle a wide range of financial challenges.

Step 1: Understand the Spending

Ken spent 50% of his remaining amount after the donation. This means the $1200 represents the other 50% (or half) of the amount he had after donating to charity. To solve this, we need to understand the relationship between the amount Ken spent and the amount he has left. If he spent 50%, the remaining 50% is equivalent to $1200. Understanding percentages and their relationship to fractions and decimals is crucial for solving financial problems. In this case, 50% can be expressed as 1/2 or 0.5. This understanding allows us to easily convert percentages into forms that can be used in calculations. Furthermore, it's essential to recognize that the remaining amount represents a portion of the total amount after the donation. By identifying this relationship, we can set up an equation to solve for the total amount. This step-by-step approach highlights the importance of breaking down complex problems into smaller, more manageable parts. By focusing on one aspect of the problem at a time, we can gain a clearer understanding of the overall situation and develop an effective solution strategy. Ultimately, this approach enhances our problem-solving skills and enables us to tackle a wide range of financial challenges with confidence.

Step 2: Calculate the Amount Before Spending

If $1200 is 50%, then the amount before spending is:

Amount before spending = $1200 / 0.50 = $2400

So, Ken had $2400 after donating to charity but before spending 50% of it. This calculation reveals the amount Ken had immediately after making his charitable donation. This figure is a crucial stepping stone in determining his original salary. Accurate calculations are essential in financial planning and management. Any errors in calculations can lead to inaccurate assessments of your financial situation and potentially flawed decisions. Therefore, it's crucial to double-check your work and ensure that you are using the correct formulas and methods. In this case, dividing the remaining amount by 0.50 (or multiplying by 2) allows us to determine the amount Ken had before spending. This step demonstrates the importance of understanding the relationship between different financial concepts and applying the appropriate mathematical operations. By carefully retracing the steps, we can build a clear picture of Ken's financial situation and ultimately determine his original salary. This methodical approach enhances our problem-solving skills and allows us to tackle complex financial challenges with confidence.

Step 3: Calculate the Original Salary

We know that $2400 represents the amount Ken had after donating 20% of his salary. Let's denote Ken's original salary as x. Then:

x - 0.20x = $2400

This equation represents the relationship between Ken's original salary (x), the 20% he donated, and the $2400 he had remaining. To solve for x, we first need to simplify the equation. Algebraic equations are a powerful tool for solving financial problems and other mathematical challenges. By representing unknown quantities with variables, we can set up equations that describe the relationships between different values. In this case, we use the variable x to represent Ken's original salary. The equation x - 0.20x = $2400 expresses the fact that Ken's remaining amount ($2400) is equal to his original salary minus the 20% he donated. Solving this equation involves simplifying the expression on the left side and then isolating the variable x. This process demonstrates the importance of understanding algebraic principles and applying them to real-world problems. By mastering these techniques, we can solve a wide range of financial challenges and make informed decisions about our financial lives.

Step 4: Solve for x

Combine the terms:

0. 80x = $2400

Divide both sides by 0.80:

x = $2400 / 0.80 = $3000

Therefore, Ken's original salary was $3000. This calculation reveals Ken's initial income before any deductions or spending. Accurate solutions are crucial in financial planning and decision-making. In this case, determining Ken's original salary allows us to fully understand his financial situation and assess the impact of his donations and spending habits. The process of solving for x involved dividing both sides of the equation by 0.80. This is a fundamental algebraic technique used to isolate the variable and find its value. By applying this technique, we can confidently determine that Ken's original salary was $3000. This information can then be used to further analyze Ken's finances, including his savings rate, debt levels, and overall financial health. Ultimately, mastering these mathematical skills is essential for effective financial management and achieving your financial goals.

In conclusion, we have successfully calculated that 80% of Ken's salary remained after his charitable donation. Additionally, we determined that Ken's original salary was $3000, given the information about his spending and remaining funds. These calculations provide a clear picture of Ken's financial situation and highlight the importance of understanding personal finance principles.
