Question

At best buy, 7 packs of Pokemon cards cost $28. At amazon, you can buy 12 packs for $38. which is the better buy per pack?

Answer 1

amazon

Explanation:

let's find the price per pack to solve

best buy:

7 packs = 28 dollars

divide both sides by 7 to get 1 pack = something

1 pack = 4 dollars

amazon:

12 packs = 38 dollars

divide both sides by 12 to get 1 pack = something

1 pack = 38/12 dollars = 3.16666666667 dollars which is less than 4 dollars, so amazon is cheaper in terms of price per pack
