I need to know how much will my monthly payment be?

Given:
Loan = P = $48,000
Simple interest rate = r = 2% = 0.02
Time = t = 9 years
So,
The interest = I =
[tex]I=P\cdot r\cdot t=48000\cdot0.02\cdot9=8640[/tex]Total amount =
[tex]48000+8640=56640[/tex]To find the monthly payments, we will divide the total amount over the number of months of the nine years
so,
The monthly payments =
[tex]\frac{56640}{9\cdot12}=524.44[/tex]
