Answer:
$796
Step-by-step explanation:
We have been given that Marge bought a computer for $699 on the installment plan. The terms of the plan were a down payment of $100, then payments of $58 a month for 12 months.
First of all, we will find the amount paid in 12 months by multiplying $58 by 12 as:
![\text{Amount paid in 12 months}=\$58\times 12](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20paid%20in%2012%20months%7D%3D%5C%2458%5Ctimes%2012)
![\text{Amount paid in 12 months}=\$696](https://tex.z-dn.net/?f=%5Ctext%7BAmount%20paid%20in%2012%20months%7D%3D%5C%24696)
Since Marge paid $100 as down payment, so her total cost would be down payment plus amount paid in 12 months.
![\text{Marge's total cost}=\$100+\$696](https://tex.z-dn.net/?f=%5Ctext%7BMarge%27s%20total%20cost%7D%3D%5C%24100%2B%5C%24696)
![\text{Marge's total cost}=\$796](https://tex.z-dn.net/?f=%5Ctext%7BMarge%27s%20total%20cost%7D%3D%5C%24796)
Therefore, Marge's total cost was $796.
