a mechanic build a customer for 4 hours labor plus 215 for parts the total bill was for 375. how much did the mechanic charge for the labor per hour?

The mechanic charged 40 for the labor per hour.

Step-by-step explanation:

Total bill paid = 375

Working hours of labor = 4 hrs

Also, the additional charges paid on the bill = 215

So, the actual labor charge paid for 4 hour labor

Actual labor Cost = Final Bill - Additional charges

= 375 - 215 = 160

Hence, the cost paid for 4 hour labor = 160

⇒ The cost paid for 1 hour labor = 160 / 4 = 40

Or, the mechanic charged 40 for the labor per hour.
