To determine the monthly mortgage payment:

Hint :multiply the monthly mortgage payment by 12
The annual interest rate (r) on the loan, but beware that this is not necessarily the APR = interest divide by 12

Using a Loan calculator
![\begin{gathered} \mleft\lbrace100,000*.0.07/12*\mleft[1+0.07/12^{12(30)^{}}\mright]\}/\mleft\{\mleft[1+0.07/12^(12)\mleft(30\mright)\mright]-1\mright\}\mright?\text{ } \\ =\text{ \$665} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/lqih1cxzbfjujcwl14hvtrjx3pw99vspe0.png)
With a $100,000 home loan, you will pay $665 monthly and over a year , Aaron will pay 12 x $665

Therefore the payment over one year = $ 7980
