Question

The inequality 4x + 260 < 400 represents the cost to repair Tom’s car. The cost of parts is $260 and it will take 4 hours of work. If x represents the labor cost per hour and Tom needs to keep the total under $400, what is the highest labor cost per hour that he can afford?

Answer 1

Answer: The highest labor cost per hour that he can afford is $34

Explanation:

Hi, to answer this question we simply have to solve the inequality:

4x + 260 < 400

4x < 400-260

4x < 140

x < 140/4

x < 35

Since x represents the labor cost per hour , The highest labor cost per hour that he can afford is $34 (using whole numbers, because x must be less than 35, not less or equal)
