Verified step by step guidance1
Identify the formula for calculating the present value of a single sum: \( PV = \frac{FV}{(1 + r)^n} \), where \( PV \) is the present value, \( FV \) is the future value, \( r \) is the annual interest rate, and \( n \) is the number of years.
Substitute the given values into the formula: \( FV = 1 \), \( r = 0.08 \) (8% annual interest rate), and \( n = 5 \) years.
Simplify the denominator by calculating \( (1 + r)^n \): \( (1 + 0.08)^5 \).
Divide the future value (\( FV = 1 \)) by the result of \( (1 + 0.08)^5 \) to find the present value.
Interpret the result as the present value of \$1 to be received in 5 years, discounted at an annual interest rate of 8% compounded annually.
