Answer:
18,375
Explanation:
I'm not sure what kind of currency P is, but the calculations should be the same as if they were dollars.
future value for simple interest = principal x interest rate x time = 15,000 x 9% x 2.5 years = 3,375 (interests only)
the total amount of interests + principal = 15,000 + 3,375 = 18,375
the difference between simple and compound interest is that when interests compounds, earned interest will start earning more interest themselves. While when calculating simple interest, interests only accumulate but do not earn any further interests. E.g. the future value of this debt using compound interest = 15,000 x 1.09²°⁵ = 18,606.19
The amount that he owes at the end of the time is $18,375.
Simple interest = Principal * Interest rate * Time
Simple interest = $15,000 x 9% x 2.5 years
Simple interest = $3,375.
Amount owed = Simple interests + Principal
Amount owed = $15,000 + $3,375
Amount owed = $18,375
Therefore, the amount that he owes at the end of the time is $18,375.
