There are 160 tissues inside a tissue box. If Tucker bought 3 boxes, and used 210 tissues while he was sick with the flu, how many tissues would he have left? Give me reasons, before answering the question
When Tucker buys the tissue boxes, he has a total of 160 x 3 = 480 tissues. When he is sick with the flu and uses some of the tissues, he has 480 - 210 = 270 tissues left. So the final answer is 270.
