Maddy's 4th grade class needs to make 1000 Valentine's Day cards to get a pizza party. There are 30 kids in the class. If everyone makes 8, how many more cards will they need to make to get a pizza party?
If 30 kids each make 8 cards, they will have made 240 cards because 30*8 = <<30*8=240>>240.
Since 1000-240 = <<1000-240=760>>760, they need to make 760 more cards.
