Answer:

A, B and F.

Step-by-step explanation:

The bill total + 20% of the bill total must be less than or equal to $60.

So we have the inequality:

x + 0.20x ≤ 60

1.20x ≤ 60

x ≤ 60/1.20

x ≤ 50 dollars.

The horizontal line has equation $y=3$ . The line is solid, and everything below it is shaded, which translates to the inequality $y\le3$ . (so not B nor D)

The dashed line must have equation $y=2x-1$ . Because it's dashed, the inequality is strict. Pick any point in the shaded region, (0, 0) for instance, and compare both sides of this equation. (0, 0) means both $x=0$ and $y=0$ , so on the left side we have 0, and on the right we have -1. 0 > -1, so the inequality must be $y>2x-1$ .
