Question

Miss Chang ordered a pizza to share with some Grade 8 students. Miss Chang

gave Michael some slices of pizza. Miss Chang gave Amy twice as many slices of

pizza as Michael. Miss Chang gave Mr. Au three times the sum of what she gave

to Michael and Amy. Miss Chang gave 60 slices of pizza to Michael, Amy and Mr.

Au in total. How many slices of pizza Miss Chang give to each person?

Answer 1

Michael: x
Amy: 2x
Mr. Au: 3(2x+x)
x+2x+3(2x+x)=60
x+2x+3(3x)=60
x+2x+9x=60
12x=60
x=5
Michael: 5 slices
Amy: 2(x)
2(5)=10 slices
Mr. Au: 3(2x+x)
3(10+5)=45 slices
