on Saturday, she worked for 4.5 hours

Step-by-step explanation:

Let x represent the number of hours that she worked after school.

Let y represent the number of hours that she worked on Saturday.

Last week, she worked for a total of 12 hours. This means that

x + y = 12

Marlee makes 5 dollars an hour working after school and 6 dollars an hour working on Saturdays. Last week she made 64.50 dollars after 12 hours of work. This means that

5x + 6y = 64.5 - - - - - - - - - -1

Substituting x = 12 - y into equation 1, it becomes

5(12 - y) + 6y = 64.5

60 - 5y + 6y = 64.5

- 5y + 6y = 64.5 - 60

y = 4.5 hours
