Question: Karen and Donald and their 6 children are sharing a beach house with Tom and Eva and their 4 children. If there are 16 legs in the pool, how many people are not in the pool? Think carefully first, then make a decision:
Karen and Donald and their 6 children are a party of 1 + 1 + 6 = 8 people. Tom and Evan and their 4 children are a party of 1 + 1 + 4 = 6 people. All total, there are 8 + 6 = 14 people at the beach house. There are 16 legs in the pool and everyone has 2 legs so there are 16 / 2 = 8 people in the pool. There are 14 people total at the beach house and 8 people are in the pool so 14 - 8 = 6 people are not in the pool. So the answer is 6.
