Get ready for a long problem. So First, We need to add up all of the fractions. We do this by making them into improper fractions. You should end up with 21/12, 28/12, and 17/12. Then you add them. You should have a total of 61/12. To make that back into a mixed number, you come up with 5 1/12 hours total. Then we multiply 5 1/12 by 10.5 ($10.50 per hour). You should then roughly come up with $53.38.
