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 the teachers 1 1/2 sheets each. Which inequality describes the number of teachers, t, Noor could give sheets of stickers to?

Answer 1

15+3/2t ≤21

Explanation:

Answer 2

`t\leq 4\ teachers`

Explanation:

Let

t-------> the number of teachers

we know that

Noor gave
`1/3` of a sheet to each of the
`45` students at recess

so

the total number of sheets given to students equals to

`45*(1)/(3)=(45)/(3)=15\ sheets`

The remain sheets is equal to

`21-15=6\ sheets`

To find the maximum number of teachers divide the remain sheets by
`1(1)/(2)` sheets

remember that

`1(1)/(2)=1.5`

so

`6/1.5=4\ teachers`

therefore

the inequality is equal to

`t\leq 4\ teachers`
