Come up with a question and reasoning that would justify [150] as the answer.
The question is: James buys steaks for buy one get one free. The price is $15 per pound and he buys 20 pounds. How much did he pay for the steaks?

Come up with a question and reasoning that would justify [11] as the answer.
The question is: Jame is trying to learn to tear playing cards. He can tear 30 cards at a time. A new deck of cards has 55 cards if you include the jokers and blank cards. He tears cards 3 times a week. If he buys 18 decks how many weeks can he go?
Reasoning: He tears 30 * 3 = 90 cards a week. He bought 55 * 18 = 990 cards. So he can tear for 990 / 90 = 11 weeks.

Come up with a question and reasoning that would justify [220] as the answer.
The question is: The age difference between Asaf and Alexander's age is half the total number of pencils Asaf has. The sum of their ages is 140, and Asaf is 50 years old. If Alexander has 60 more pencils than Asaf, calculate the total number of pencils they have together.
Reasoning: If the sum of their ages is 140, and Asaf is 50 years old, Alexander is 140 - 50 = 90 years old. The age difference between Asaf and Alexander's age is 90 - 50 = 40. Since the age difference between Asaf and Alexander's age is half the total number of pencils Asaf has, Asaf has 2 * 40 = 80 pencils. If Alexander has 60 more pencils than Asaf, Alexander has 80 + 60 = 140 pencils. Together, they have 140 + 80 = 220 pencils.
