Question

A pack of paper costs $3.75 including tax. Mr. Cooper wants to purchase packs of paper for his class and has a $20 budget. Write an inequality to solve for the number of packs of paper Mr. Cooper can purchase with his budget.

Answer 1

3.75p<=20

divide by 3.75

p < 5 1/3

he can purchase 5 packs of paper

Answer 2

`3.75x\leq 20`

5 packs of paper.

Explanation:

Let x be the number of packs of paper.

We have been given that a pack of paper costs $3.75 including tax. The price of x paper packs would be
`3.75x`.

Since Mr. Cooper has a $20 budget, so the cost of x paper pack should be lees than or equal to 20.

We can represent this information in an inequality as:

`3.75x\leq 20`

`(3.75x)/(3.75)\leq (20)/(3.75)`

`x\leq 5.333`

Since we can purchase whole number of paper packs, therefore, Mr. Cooper can purchase 5 packs of paper with his budget.
