Question

Tim bought 5 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 27 cards left. How many cards did Tim start with?

Answer 1

So if the dog ate half his collection and Tim now had 27 cards left if we times it by two we will get the number of cards he had including the 5 new ones so:

27 x 2 = 54 and then if we take the 5 new ones away we get 49 so Tim had 49 cards at the start

ANSWER: 49 cards
