There are 3 cubes, 2 pyramids, 4 cylinders, 2 cones, and 2 rectangular prisms. The total number of cubes, cylinders, and cones is 9. There were originally 9 balls on the field but 2 were hit over the fence, so there are now 7 balls left. There are 4 football teams with 2 players each, so the parent will need to buy 8 ice cream cones. Mrs. Smith bought 15 cans of food and is giving them to 3 people, so each person will get 5 cans.
