Doug earns $10.50 per hour working at a restaurant. On

alexira [117]

First, add all of the working hours.
1 $\frac{3}{4}$ + 2 $\frac{1}{3}$ + 1 $\frac{5}{12}$

Since the denominators are different, make them all the same.
1 $\frac{9}{12}$ + 2 $\frac{4}{12}$ + 1 $\frac{5}{12}$

Add everything together.
4 $\frac{1}{12}$ + 1 $\frac{5}{12}$ = 5 $\frac{6}{12}$

Then, simplify.
5 $\frac{1}{2}$ or 5.5

Multiply the time by the salary.
<span>5.5*10.5= Doug earned $57.75</span>
