The inequality that represents the amount of money Alex needs to earn is y = 11.50x and 9x + 100.
<h3>How to depict the information?</h3>The slope and the y intercept of both of the works will be:
For the tech company:
y = 11.50x
m = 11.50
y = 11.50(8 × 20)
y = 11.50(160)
y = 1840
For the amusement park
amusement parky = 9x + 100
amusement parky = 9x + 100y = 9(320) + 100
y = 2880 + 100
y = 2980.
When he wants to make the exact amount, the number of hours will be:
9x + 100 = 2200
9x = 2200 - 100
9x = 2100
x = 233.3
