Answer:
The student will have to reimburse 2,991.03 two years later.
Step-by-step explanation:
This is a compound interest problem:
The compound interest formula is given by:
In which A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.
In this problem, we have that:
A is the amount the student will have to reimburse two years later.
P is his loan. so
The bank loans this money at a rate of 9 % capitalized monthly. This means that and
, since the money is compounded monthly, this means, 12 times in a year.
He will have to reimburse two years later, so
The student will have to reimburse 2,991.03 two years later.
