Write an inequality expression based on the problem$2,500 is a fixed cost, it will be the constant of the inequality. $20 is a variable cost because it changes every hour. For an instance, x hour is the maximum amount of hours. The inequality will be:
2,500 + 20x ≤ 6,000
Solve the value of x2,500 + 20x ≤ 6,000
substract both sides by 2,500
2,500 - 2,500 + 20x ≤ 6,000 - 2,500
20x ≤ 3,500
divide both sides by 20

x ≤ 175
The maximum amount of hours is 175
