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 1/2 sheets each.

Answer 1

Answer:

$t\leq 4\ teachers$

Step-by-step explanation:

the question is

 Which inequality describes the number of teachers, t, Noor could give the stickers to?

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

$45*\frac{1}{3}=\frac{45}{3}=15\ sheets$

The remain sheets is equal to

$21-15=6\ sheets$

To find the maximum number of teachers divide the remain sheets by $1\frac{1}{2}$ sheets

remember that

$1\frac{1}{2}=1.5$

so

$6/1.5=4\ teachers$

therefore

the inequality is equal to

$t\leq 4\ teachers$

Answer 2

Answer:

t less than or equal to 4

15+3/2t is less than or equal to 21
