Marine bought 8 packs of baseball cards at a garage sale Each pack had 10 cards .he gave his younger sister 3 cards from each pack. How many cards does Jerome have left?
8 times 10 is 80 so we now have to find how much does his sister has so if she get 3 cards from each pack. So we multiply 3 times 8 which equals 24. So 80 minus 24 equals 56 cards.
