My question is: Greg and Sarah have 18 apples that they are going to split evenly. Susan has twice as many apples as Greg will end up with. Mark has 5 fewer apples than Susan. Their mom needs 40 apples to make an apple pie. How many will she have left over? Your thoughts:

Greg and Sarah will split their apples, so 18 apples / 2 = 9 apples per child. Susan has 2 * 9 apples = 18 apples. Mark has 18 apples - 5 apples = 13 apples. Combined the children have 9 apples + 9 apples + 18 apples + 13 apples = 49 apples. Mom will have 49 apples - 40 apples = 9 apples left over. The final answer: 9.
