Answer:$57.75

Step-by-step explanation:

Find the total amount of hours he worked

$1\frac{5}{12} +1\frac{3}{4} +2\frac{1}{3}\\\\\frac{17}{12}+ \frac{7}{4} +\frac{7}{3} \\\\\frac{17+21+28}{12} \\\\\frac{66}{12}=\frac{66/2}{12/2}=\frac{33/3}{6/3}= \frac{11}{2} or 5\frac{1}{2} or 5.5h$

So, he worked 5.5h and he earns $10.50 an hour.

($10.50)(5.5h)=$57.75
