Question

Noor brought 21 sheets of stickers. She gave 1/3 of a sheet to each of the 45 students at recess. She wants to give teachers 1 and 1/2 sheets each. Which inequality describes the number of teachers, t, Noor could give the stickers to?

Answer 1

start with 21 sheets

1/3 of a sheet per 45 students ---> 1/3 * 45 sheets given out

therefore, after giving away those stickers she's got 21 - 1/3 * 45 stickers left

that quantity, divided by 1 and 1/2, will give you the maximum value t for the number of teachers
