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.

Answer 1

($3.75)n ≤ $20

Explanation:

Represent this number by n. Then the total purchase price can be represented by ($3.75)n ≤ $20, which is appropriate because Cooper can't spend more than $20.

The desired inequality is ($3.75)n ≤ $20. If a solution is desired, divide both sides by $3/75):

$20

n ≤ ______ = 5 1/3.

$3.75

Cooper can purchase up to 5 whole packs of paper and have a bit of money left over.
