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.
5.5*10.5= Doug earned $57.75
