Stella needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3.25 hours and charged her $75 for parts.
The total was $188.75. What was the cost of labor, per hour?

9514 1404 393

  $35 per hour

Step-by-step explanation:

The total charge is the sum of costs of parts and labor. If h is the cost of a labor hour, then we have ...

  188.75 = 75 + 3.25h

  113.75 = 3.25h . . . . . . . . subtract 75

  113.75/3.25 = h = 35 . . . divide by the coefficient of h

The cost of labor, per hour, is $35.

it should be a and d. lmk if i'm wrong xd

y > 1/3x

y < = -x + 4

hope this : )
