Come up with a question and reasoning that would justify [1200] as the answer.
The question is: Bob orders a pizza with 8 slices. He eats half of it and each slice was 300 calories. How many calories did he eat?
Reasoning: He ate 8 / 2 = 4 slices. So he ate 4 * 300 = 1200 calories.

Come up with a question and reasoning that would justify [200] as the answer.
The question is: A craftsman makes 16 jars. This is exactly twice the number of clay pots he made. If each jar has 5 marbles and each clay pot has three times as many, how many marbles are there?
Reasoning: 16 jars are exactly twice the number of clay pots made by the craftsman, meaning there are 16 / 2 = 8 clay pots. If each jar has 5 marbles, the total number of marbles in the jars is 5 * 16 = 80. Each of the clay pots also has 3 * 5 = 15 marbles. The total number of marbles in the 8 clay pots is 15 * 8 = 120. There are a total of 120 + 80 = 200 marbles.

Come up with a question and reasoning that would justify [12] as the answer.
The question is: Kurt's old refrigerator cost $0.85 a day in electricity. He recently bought a new energy-efficient refrigerator that only cost $0.45 a day in electricity. How much money does Kurt save in a 30-day month with his new refrigerator?
Reasoning: The old refrigerator costs $0.85 a day so for 30 days it costs .85 * 30 = $25.50. The new refrigerator costs $0.45 a day so for 30 days it costs .45 * 30 = $13.50. Over 30 days, Kurt saves 25.50 - 13.50 = $12.00 a month with his new refrigerator.
