Acme inc. is charged $2,500 plus $20 per hour by a company repairs their computers. if their budget for computer repair is $6,000, what is the maximum amount of hours of computer repair can they afford?

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 x
2,500 + 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

Really any number between them works. for example 144.951
