Answer:
$69.88
Explanation:
Calculation to determine the interest on interest if interest is compounded
First step is to calculate Simple interest per year
Deposit today represent PV = $5,000
Interest rate represent i = 6.75%
No. of years represent n = 3
Simple interest per year = $5,000 × (0.0675)
Simple interest per year= $337.50
Second step is to calculate the Simple interest for 3 years
Simple interest for 3 years = $337.50 × 3
Simple interest for 3 years= $1,012.50
Fourth step is to calculate the Future value with compound interest (FV3)
FV3 = $5,000 (1 + 0.0675)^3
FV3=$5,000+(1.0675)^3
FV3= $6,082.38
Now let determine the Interest on interest
Interest on interest = $6,082.38 - $5,000 - $1,012.50
Interest on interest = $69.88
Therefore the interest on interest if interest is compounded is $69.88
