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?
How much does each pack cost? ** Each pack cost 20*10=<<20*10=200>>200 cents
How much does each pack cost? ** So each pack cost 200/100=$<<200/100=2>>2
How much did Josh pay? ** That means he pays 2*3=$<<2*3=6>>6
