Introduction

When it comes to investing, understanding the returns on investment (ROI) is crucial in making informed decisions. In this article, we will compare the investment returns of two individuals, Tasha and Thomas, who have invested different amounts at varying interest rates. We will analyze their investment portfolios and determine which statement accurately compares their returns.

Tasha's Investment Portfolio

Tasha has invested a total of $\$10,000$ in two separate accounts. The first account has a principal amount of $\$5,000$ and an annual interest rate of $6\%$ . The second account has a principal amount of $\$5,000$ and an annual interest rate of $8\%$ . To calculate the total return on investment for Tasha, we need to calculate the interest earned on each account and add them together.

Calculating Interest Earned on Each Account

To calculate the interest earned on each account, we can use the formula:

Interest = Principal x Rate x Time

Since the time period is not specified, we will assume that the interest is compounded annually for a period of 1 year.

For the first account with a principal amount of $\$5,000$ and an annual interest rate of $6\%$ , the interest earned is:

Interest = $\$5,000$ x $0.06$ x $1$ = $\$300$

For the second account with a principal amount of $\$5,000$ and an annual interest rate of $8\%$ , the interest earned is:

Interest = $\$5,000$ x $0.08$ x $1$ = $\$400$

Total Return on Investment for Tasha

To calculate the total return on investment for Tasha, we add the interest earned on each account:

Total Return = $\$300$ + $\$400$ = $\$700$

Total Amount Invested by Tasha

The total amount invested by Tasha is the sum of the principal amounts in both accounts:

Total Amount Invested = $\$5,000$ + $\$5,000$ = $\$10,000$

Return on Investment (ROI) for Tasha

To calculate the ROI for Tasha, we divide the total return on investment by the total amount invested:

ROI = $\$700$ / $\$10,000$ = $0.07$ or $7\%$

Thomas's Investment Portfolio

Thomas has invested a total of $\$10,000$ at an annual interest rate of $7\%$ . To calculate the return on investment for Thomas, we can use the formula:

Interest = Principal x Rate x Time

Since the time period is not specified, we will assume that the interest is compounded annually for a period of 1 year.

Interest = $\$10,000$ x $0.07$ x $1$ = $\$700$

Total Return on Investment for Thomas

The total return on investment for Thomas is the interest earned:

Total Return = $\$700$

Total Amount Invested by Thomas

The total amount invested by Thomas is the principal amount:

Total Amount Invested = $\$10,000$

Return on Investment (ROI) for Thomas

To calculate the ROI for Thomas, we divide the total return on investment by the total amount invested:

ROI = $\$700$ / $\$10,000$ = $0.07$ or $7\%$

Comparing Investment Returns

Now that we have calculated the ROI for both Tasha and Thomas, we can compare their investment returns. The statement that accurately compares their returns is:

Tasha's ROI is lower than Thomas's ROI.

This is because Tasha's total return on investment is $\$700$ , which is lower than Thomas's total return on investment of $\$700$ . However, when we calculate the ROI, we get the same result for both Tasha and Thomas, which is $0.07$ or $7\%$ . This is because the total return on investment is the same for both, but the total amount invested is different.

Conclusion

In conclusion, when comparing the investment returns of Tasha and Thomas, we need to consider the total return on investment and the total amount invested. While Tasha's total return on investment is lower than Thomas's, their ROI is the same. This highlights the importance of understanding the ROI and not just focusing on the total return on investment when comparing investment returns.

Recommendations

Based on the analysis, we can make the following recommendations:

Tasha should consider investing in a single account with a higher interest rate to maximize her returns.
Thomas should consider diversifying his investment portfolio to minimize risk and maximize returns.

By following these recommendations, Tasha and Thomas can optimize their investment portfolios and achieve their financial goals.
