Question

the car you just bought keeps breaking down. the parts you need to buy cost $408.97. your mechanic also charges $53 per hour for labor. which of these equations best shows the cost to fix your car? repair charge = -53·hours of labor + 408.97 repair charge = 53 + hours of labor·408.97 repair charge = 53·hours of labor + 408.97 repair charge = 53·hours of labor - 408.97

Explanation:

Step1: Analyze the cost components

The cost of parts is a fixed cost of $408.97. The labor cost is $53 per hour. If the number of hours of labor is \(h\), the labor cost is \(53h\).

Step2: Form the total cost equation

The total cost \(C\) (repair charge) is the sum of the cost of parts and the labor cost. So, \(C = 53h+408.97\)

Answer:

Repair Charge \(= 53\cdot\) Hours of Labor \(+ 408.97\) (the third option)
