    Rearranging the options we have;

    a. $73

    b. $75

    c. $55

    d. $78

    From which the correct option is;

    b. $ 75.

    Step-by-step explanation:

    To solve the question, we note that

    Number of hours worked last week by Maria = 15 Hours

    Amount earned by Maria for work last week = $ 112.50

    Therefore by finding the hourly rate, that is how much Maria is being paid per hour, we get

    15 Hours = $ 112.50

    Therefore dividing both sides of the equation by 15 we get

    15 Hours/15 = $ 112.50/15 which gives

    1 Hour = $ 7.50

    To find out how much will she earn if she works for 10 hours, we have

    1 Hour = $ 7.50

    Therefore multiplying both sides of the equation by 10 we have,

    1 Hour * 10 = $ 7.50 * 10

    10 hours = $ 75.00

    That is she would earn $ 75.00 in 10 hours.
