Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Present value(PV)= $7,000
Number of periods (n)= 4 years
Interest rate (i)= 8% annually
To calculate the future value of the investment, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 7,000*(1.08^4)
FV= $9,523.42
Now, the interest earned:
Interest earned= FV - PV
Interest earned= 9,523.42 - 7,000
Interest earned= $2,523.42
