Come up with a question and reasoning that would justify [25] as the answer.
The question is: Frank's laundry detergent is double concentrated and will wash 80 loads of laundry. His detergent is usually $25.00 a bottle but they're having a sale. If he buys 2 bottles, both bottles will drop to $20.00 a bottle. How much does he spend, in cents, per load of laundry, if he buys 2 bottles of detergent?
Reasoning: If he buys 2 bottles, the price drops to $20.00 per bottle so they cost 2 * 20 = $40.00. He can get 80 loads of laundry per bottle and he bought 2 bottles so that's 80 * 2 = 160 loads of laundry. The detergent cost $40.00 and he will be able to wash 160 loads of laundry so each load costs 40 / 160 = $0.25.

Come up with a question and reasoning that would justify [6] as the answer.
The question is: 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?
Reasoning: 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.

The question is: James spends 40 years teaching. His partner has been teaching for 10 years less. How long is their combined experience?
Reasoning: His partner has been teaching for 40 - 10 = 30 years. So together they have 40 + 30 = 70 years of experience.
