Answer:

PV= $29,454.44

Explanation:

Giving the following information:

Cash flow= $3,000

Number of years= 20

Interest rate= 6%

Growth rate= 2%

To simplify calculations, we will sum the growing rate to the interest rate.

Real interest rate= 8%

To determine the present value, first, we need to calculate the final value using the following formula:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

FV= {3,000*[(1.08^20)-1]} / 0.08

FV= $137,285.893

Now, the present value:

PV= FV/(1+i)^n

PV= 137,285.893/1.08^20

PV= $29,454.44
