My question is: A carton contains 12 boxes. If each box has 10 packs of cheese cookies, what's the price of a pack of cheese cookies if a dozen cartons cost $1440? Your thoughts:
If 1 carton contains 12 boxes, then a dozen cartons contain 12 * 12 = 144 boxes. If 1 box has 10 packs of cookies, then 144 boxes have 144 * 10 = 1440 packs. If a dozen cartons cost $1440 and contain 1440 packs of cookies, then each pack costs 1440 / 1440 = $1. The final answer: 1.
