Question: Josh buys 3 packs of string cheese. Each piece of string cheese cost 10 cents. Each pack has 20 string cheeses in them. How many dollars did he pay? Think carefully first, then make a decision:
Each pack cost 20 * 10 = 200 cents. So each pack cost 200 / 100 = $2. That means he pays 2 * 3 = $6. So the answer is 6.
