Answer:
The correct option is 72.
Step-by-step 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.
