9514 1404 393

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.

Ugo [173]

Answer:

36\:\mathrm{in^3}

Step-by-step explanation:

A=\frac{1}{2}\cdot 3\cdot 4=6\:\mathrm{in^2}

The height is marked as 6 inches. Thus, the volume of the prism is:

\frac{1}{2}\cdot 3\cdot 4\cdot 6=\boxed{36\:\mathrm{in^3}}
