Explanation:

-Total cost of repayment: $9,948.48

-Interest: $948.48

Step-by-step explanation:

As Christina took a loan with a 4-year term with monthly payments of $207.26, you can find the total cost of repayment by multiplying the monthly payments for 48 months:

$207.26*48= $9,948.48

The interest that Christina will pay on her loan can be calculating by subtracting the principal from the total cost of repayment:

$9,948.48-$9,000= $948.48
