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. how much was her total cost?

$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:

Since Marge paid $100 as down payment, so her total cost would be down payment plus amount paid in 12 months.

Therefore, Marge's total cost was $796.

(3x-8) or (3x+8)

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
