Answer:
 P=R(1-(1+i)^-n/i)      Â
Explanation:
Where P=8,470
R=Monthly installment
I=7.5%
N=10*12=120
By using above data we get R=$100.54 per month
Answer:
Since the interest varies every month, it will be too long to write down how much she will save, but on the attached spreadsheet you can find the amount saved during the first 54 months. Â
Viola will save $2,382.84 during the 54 months that the government will subsidize her loan.
Explanation:
The current rate for direct subsidized or direct unsubsidized undergraduate loans (4 years) is 4.53%.
The advantage of a subsidized loan is that the government pays the interest during the first 4 and a half years, so Viola will pay only principal. Since the question gave us a 7.5% rate, I will use that rate to calculate the monthly payment on an excel spreadsheet.
The monthly payment for both loans is $100.54, but Viola will have a discount during the first 54 months. The interest varies monthly, but the total amount of interest that she will save during the first 54 months (4 1/2 years) is $2,382.84.
