Question

How do I solve these problems I'm trying to find the cheapest deal

Answer 1

2.79 / 2 = 1.395 rounds to 1.40 per roll
8.99 / 6 = 1.498 rounds to 1.50 per roll

the better deal (cheapest) is the 2 roll package

** if u want price per roll (price / roll) ...u divide the price by the number of rolls

Answer 2

Take the total price and divide by the number of rolls that will tell you the price per roll
