Instructions are below.

Explanation:

Giving the following information:

Value at 18 = $3,996

Interest rate = 8%

To calculate the final value, we need to use the following formula:

FV = PV * (1+i) ^n

A) Number of years = 7

FV = 3,996 * (1.08^7) = $6,848.44

B) Number of years = 47

FV = 3,996 * (1.08^47) = $148,779.12

C) Finally, we need to determine the original investment. We need to isolate the present value from the formula:

PV = FV / (1+i) ^n

PV = 3,996 / (1.08^18)

PV = $999.995
