Compute the future value of $800 at an interest rate of 5 percent 5,10 , and 15 years into the future. What would the future value be over these time horizons if the interest rate were 3 percent? Instructions: Enter your responses rounded to the nearest penny (two decimal places). Do not round intermediate calculations. At an interest rate of 5 percent Future value in 5 years =$ Future value in 10 years =$ Future value in 15 years =$ At an interest rate of 3 percent: Future value in 5 years =$ Future value in 10 years =$ Future value in 15 years =$ The patterns over different time horizons and at different interest rates show that as the time horizon lengthens, the future value As the interest rate declines, the future value
