Answer:

Books'R'Us is proportional. Bargains'R'Us is not proportional.

Step-by-step explanation:

Susan buys books at two stores. At Books'R'Us, she can buy a book for $1.25 each. At Bargains'R'Us, she made a deal to buy a set of 3 books for $4.00 and a set of 5 books for $5.00.

Book'R'Us is proportional because each book costs a consistent value of $1.25. 0 books is $0. 1 book will be $1.25 and 2 books will be $2.50 and 3 books will be $3.75.

Bargains'R'Us is not proportional because each book has a different price depending on the bargain. Though 0 books is $0, a set of 3 costs $4.00 or $1.34 a book. A set of 5 costs $5.00 or $1 per book. The cost is not consistent or constant. It changes from situation to situation. This is not proportional.

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
Tamiku [17]

Answer:

\frac{3}{2}t+15\leq 21

Step-by-step explanation:

Let t represent the number of teachers.

We have been given that Noor gave 1/3 of a sheet to each of the 45 students at recess.

Let us find the number of sheets given to students by Noor by multiplying the total number of students by the part of sheet given to each student.

\text{Number of sheets given to 45 students}=45\times \frac{1}{3}

\text{Number of sheets given to 45 students}=15

So, Noor gave 15 sheets to 45 students.

We have been given that Noor wants to give 1\frac{1}{2}=\frac{3}{2} sheet to each teachers, so the number of sheets given to t teachers will be \frac{3}{2}t.

As Noor has bought 21 sheets, so the number of sheets given to students and t teachers will be less than or equal to 21.

We can represent this information in an inequality as:

\frac{3}{2}t+15\leq 21

Therefore, the inequality \frac{3}{2}t+15\leq 21 represents the number of teachers ,t, Noor could give sheets of stickers too.
