Heather works as a waitress at her family’s restaurant. She works 2 hours every morning during the breakfast shift and returns to work each evening for the dinner shift. In the last four 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
The answer is 5. Since she worked four days and she works 2 hours every morning, she must have worked 8 hours in just the breakfast shifts. Because she only has breakfast and evening shifts, you can conclude that 28(hours she worked in total) - 8(hours she worked in breakfast shifts) = 20(hours worked in evening shifts). Now, since there are 4 days she worked, divide 20 by 4 to get how many hours she worked every evening shift.
