Question

Heather works as a waitress at her family`s restaurant. she works 2 hours every morning during the breakfast shift and returns to work work each evening for the dinner shift. In the last 4 days ,she worked 28 hours. If Heather works the same number of hours every evening, how many hours did she work during each dinner shift?

Answer 1

First, Multiply

2 hours x 4 days = 8 hours

Subtract,
 
28 hours - 8 hours = 20 hours

Divide

20 hours ÷ 4 days = 5 hours each day.

Check you work by Multiplying and adding

5 hours x 4 days = 20

20 hours + 8 hours = 28 hours

Heather worked 5 hours each dinner shift
