Answer 1

The correct option is 72.

Explanation:

To calculate this, we first let x represent the number games that must be played to make at least $45.

Based on this, we can have an in equality equation as follows:

2.50x - 135 ≥ 45

We can now solve for x as follows:

2.50x ≥ 135 + 45

2.50x ≥ 180

x ≥ 180 / 2.50

x ≥ 72

This implies that at leats 72 games must be played to make at least $45. Therefore, the correct option is 72.
