Question

Give the answer and explanation/ equation.

Toilet paper is sold in cases of 36 rolls for $14.99. What is the price per roll (unit cost)?

Answer 1

Alright, so the unknown value here we want to know is the price of one roll of TP. Let's call it "x".
36x=14.99
Divide both sides by 36 to get the price of a single roll.
x=.41638888....
We have to round this to hundredths because we're talking in cents, so...
x=.42
Each roll of toilet paper costs 42 cents.
