Amount borrowed = $1,250
Amount paid per payment = $45.15
Number of times payment was made = 36
This implies
The total amount paid is
[tex]36\times\text{\$}45.15=\text{\$}1625.40[/tex]Hence, the total amount paid = $1,625.40
Interest is calculated using
Interest = Total amount paid - Amount borrowed
Hence, the interest is
[tex]\begin{gathered} I=\text{\$}1625.40-\text{\$}1250 \\ I=\text{\$}375.40 \end{gathered}[/tex]Therefore, the interest she paid is $375.40
