The amount of the stereo is $767.
A down payment of 20% was made,that means;
[tex]\begin{gathered} \text{Deposit}=767\times\frac{20}{100} \\ \text{Deposit}=767\times0.2 \\ \text{Deposit}=153.40 \end{gathered}[/tex]The amount she financed therefore is the difference between the total cost and her down payment.
Finance amount = 767 - 153.40
Finance amount = $613.60
The correct answer is option D
