The loan amount is given as $76521
We first have to calculate the total amount of tuition
6970 x 4 + 11320 x 4
= 73160
[tex]73160 (1+\frac{\frac{4.5}{100} }{12} )^1^2[/tex]
= 73160 x (1 + 0.00375)¹²
= 76520.95
Hence the new loan amount after agrace period of 1 year = $76521
b. PV = $76521
i = [tex]\frac{4.5/100}{12}[/tex]
= 0.00375
t = 10 years
[tex]PMT[\frac{1-(1+0.00375)^-^1^2^0}{0.0375} ]= 76521[/tex]
pmt = 793. 05
The monthly payment is $793. 05.
In ten years the total payment is 793.05 x 10 x 12
= 95166
Difference = 95166 - 76521
= $18645
In ten years her ,monthly payment on the loan would be $18645.
