Adam has $300 when he entered the store. He spent $72 on some CD's. He wants to use the rest of the money to buy some DVD's. If DVD's cost $18 each, which would be the best way for Adam to find how many DVD's he can afford to buy?

B.Add 300 to 72 then subtract 18
C.Subtract 72 from 300 then divide by 18
D.Add 72 to 300 then divide by 18
