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
