An adverse market delivery charge rate depends

on the credit score of the borrower, the

amount borrowed, and the loan$-$to$-$value $($LTV$)$

ratio. The LTV ratio is the ratio of amount borrowed

to appraised value of the home. For example, a

homebuyer who wishes to borrow $$250,000$ with a

credit score of $730$ and an LTV ratio of $80\%$ will

pay $0\mathrm{.}75\%(0\mathrm{.}0075)$ of $$250,000$ or $$1875.$ The

table below shows the adverse delivery charge for

various credit scores and an LTV ratio of $80\%.$

Answer parts $($a$)$ through $($c$).$

$($a$)$ Construct a function $C=C($s$)$ where $C$

is the adverse market delivery charge and

$s$ is the credit score of an individual who

wishes to borrow $$300,000$ with an $80\%$

LTV ratio.

$($b$)$ What is the adverse market delivery

charge on a $$300,000$ loan with an $80\%$

LTV ratio for a borrower whose credit score

is $701?$

$

$($c$)$ What is the adverse market delivery

charge on a $$300,000$ loan with an $80\%$

LTV ratio for a borrower whose credit score

is $672?$
