Toillet paper is sold in cases for 36 rolls for $14.99 what is the per price per roll?

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.
