To calculate the total amount of money Corbin will pay over the course of the loan, we need to determine the monthly payment amount and then multiply it by the total number of payments.

First, we need to calculate the monthly interest rate. We divide the annual interest rate by 12 (the number of months in a year) and convert it to a decimal: 3.5% / 12 = 0.002917.

Next, we need to calculate the total number of payments. Since the loan term is 20 years and it is compounded monthly, the total number of payments is 20 years * 12 months = 240 payments.

Now, we can use the loan formula to calculate the monthly payment amount (PMT):
PMT = (PV * i) / (1 - (1 + i)^(-n))
where PV is the loan amount, i is the monthly interest rate, and n is the total number of payments.

Given that Corbin's loan amount is $75,000, i = 0.002917, and n = 240, we can substitute these values into the formula:
PMT = (75000 * 0.002917) / (1 - (1 + 0.002917)^(-240))
PMT ≈ 426.53

The monthly payment amount is approximately $426.53.

Finally, we can calculate the total amount of money Corbin will pay over the course of the loan by multiplying the monthly payment by the total number of payments:
Total amount = PMT * n
Total amount = 426.53 * 240
Total amount ≈ $102,367.20

Therefore, Corbin will pay a total amount of approximately $102,367.20 over the course of the loan.
