Answer 1

We know that

• He charges a $45 initial fee and $32.50 per hour.

,

• He was paid $207.50.

Based on the given information, we have.

$207.50=45+32.50h$

Now, we solve for h (hours).

$\begin{gathered} 207.50-45=32.50h \\ 32.50h=162.50 \\ h=\frac{162.50}{32.50} \\ h=5 \end{gathered}$

Hence, the right answer is C. 5.
