Answer:
$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.

- Simplify ⇨ 19m + 14 - 3 (3m + 7)


Use the distributive property to multiply -3 by 3m+7.

Combine 19m and -9m to get 10m.

Subtract 21 from -14 to get -35.
