Final answer:
To calculate the amount of money your uncle would have invested with a return of 7.5%, you can use the compound interest formula. The formula is A = P(1+r/n)^(nt), where A is the final amount, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.
Step-by-step explanation:
To calculate the amount of money your uncle would have invested with a return of 7.5%, you can use the compound interest formula. The formula is A = P(1+r/n)^(nt), where A is the final amount, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years. In this case, the principal amount is $300,000, the interest rate is 7.5%, and the time period is not provided. If you have the time period, you can plug in the values and calculate the final amount. For example, if the time period is 10 years and interest is compounded annually (n = 1), the calculation would be A = 300,000(1+0.075/1)^(1*10) = $636,367.23.
