C.

Step-by-step explanation:

The answer states that she needs at least 52.50, this wording equating to it's equation having a greater than sign. This leaves us with B or C. It is most definitely not B as that involves addition which is not in use as of the given equation.

If you want the X intercept put zero on the y. If you want to find Y intercept put zero on the X

1.5x-0=10.2

5x=10.2

X=2.04

2.9(0)+3y=-18.3

3y=-18.3

Y=-6.1

3. 6(0)-4y=-12

-4y=-12

Y=3

6x-4(0)= -12

6x=-12

X=-2
