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 the teacher 1 1/2 sheets each.

The inequality that represents the word problem is the following:

15 + (3/2)t ≤ 21

Step-by-step explanation:

Because Noor gave a 1/3 of a sheet to each of the 45 students at recess this equals to 15.

45×⅓ = 15 sheets for students

And because she wants to give each teacher 1 and 1/2 sheets, that is the same as giving them 3/2.
