Benny brought five new baseball trading cards to add to his collection. the next day his dog ate half of his collection. there are now only thirty cards left. how many cards did benny start with?
Benny started with 55 five cards. In order for his dog to have eaten half his cards and end up with 30 cards, that would mean he had 60 cards. Mind you, he had bought 5 more the day before his dog ate them. I hope that makes sense
