the bill(parts and labor) for the repair of a car was $458. the cost of parts was $339. the cost of labor was $34 per hour. write and solve an equation to find the nuber of hours of labor. make sure you show your work.
To find the number of hours of labor, we can set up an equation using the given information.
Let's denote the number of hours of labor as "x". The cost of labor per hour is given as $34.
The total cost of labor can be calculated by multiplying the number of hours of labor (x) by the cost of labor per hour ($34):
Cost of labor = Number of hours of labor * Cost of labor per hour
Substituting the given values into the equation:
458 = x * 34
To solve for x, divide both sides of the equation by 34:
458 / 34 = x
Performing the calculation:
13.47 ≈ x
Therefore, the number of hours of labor required for the repair of the car is approximately 13.47 hours.
labor cost=458-339
labor hours=laborcost/34=(458-339)/34
