$13)$ Some financial advisors recommend that your monthly mortgage payment be no higher than $28\%$ of your monthly net income. What is $28\%$ of your monthly net income, as determined in question twelve? This is the estimated amount you can afford per month for a mortgage.

$4,518*0\mathrm{.}28=$ $$1,265$

$28\%$ of my monthly net income is $$1,265.$

$14)$ We can calculate how much of a house you can afford using the loan formula. In question thirteen, you determined the monthly mortgage payment you can afford. Using this value for the regular monthly payment, calculate the present value $($P$),$ assuming you receive a $30-$year mortgage $($loan$)$ with an annual interest rate of $6\mathrm{.}328\%$ with monthly compounding. $($Note: This rate is realistic for a mortgage initiated in January $2024.)$

I need to use Loan formula to find the present value $($P$).$ please help me
