Answer 1

C. repair charge = 53 * hours of labor + 408.97

Answer 2

C.)Repair Charge = 53 • Hours of Labor + 408.97

Explanation:

The question asks to write an equation to calculate the cost of repairing the car, this cost will include the cost of the parts which is fixed plus the cost of the labor of the mechanic which will depend on how many hours it takes, as the mechanic charges per hour of labor.

Repair charge = cost of mechanic labor + cost of parts

• Cost of parts = $408.97

Cost of mechanic labor is $53 per hour so

• Cost of mechanic labor = $53 × hours of labor

So the equation will be:

Repair Charge = $53 × hours of labor + $408.97

So it is answer C
