    Her hourly rate is $8.25

    Explanation:

    Tatianna works 3 hours a day on school days and makes a total of $123.75 in a week

    We know that:

    There are 5 school days in a week

    We are given that:

    She works for 3 hours a day each of those days

    Therefore:

    Total number of hours worked = hours worked daily * number of days

    Total number of hours worked = 3 * 5 = 15 hours in a week

    The equation used to calculate Tatianna's earnings is:

    Amount she makes in a week = Total number of hours worked * hourly rate

    Now, we substitute with the givens to get the hourly rate as follows:

    Amount she makes in a week = Total number of hours worked * hourly rate

    123.75 = 15 * hourly rate

    Hourly rate = $8.25
