Answer:
Her hourly rate is $8.25
Step-by-step 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
