$2,095.30 interest will she pay by the time the loan is repaid
Solution:
The $5,500 guaranteed Stafford loan is taken from Gertrude.
The loan has a monthly compounding interest rate of 6.8 percent.
Price current= $5,500.
Present Value = $5,500
Time period = 10 years
So , N = 10 x 12 = 120 months.
Interest rate, R = 6.8/1200 = 0.005666667
PV = Pmt * [1 - (1+R)^(-N)]/(R)
5500 = Pmt * [1 - (1+0.005666667)^(-120)]/(0.005666667)
Pmt = $63.29418157
She got full refund. = 63.29418157 x 120 = $7,595.30
Interest paid = Total repayment - Loan Principal
= $7,595.30 - $5,500
= $2,095.30
