    First, add all of the working hours.

    1 3/4 + 2 1/3 + 1 5/12

    Since the denominators are different, make them on all the same.

    1 9/12 + 2 4/12 + 1 5/12

    Add everything up.

    4 1/12 + 1 5/12

    5 6/12

    Simplify.

    5 1/2 or 5.5

    Multiply the time by the salary.

    5.5*10.5=57.75

    Doug earned 57.75$

    If he earns $10.50 per hour, add the number of hours he work and then divide by 10.50
