Answer: $4.50
Step-by-step explanation:
If she spent 10.50, and had 7.50 left, her total was 18.
$18/4=$4.50
Start on the y-axis and put a point at 490 bc it the y-intercept and then from there go up 2 and right 3 and put a point there and keep going and to go down you just go down 2 and left 3 and the point it.
To solve for x:
<span>C=85x+60 subtract 60 from both sides
</span>
<span>C - 60=85x+60 - 60
C - 60 = 85x now divide by 85 both sides
(C - 60)/85 = x
So we can write:

</span>
