Come up with a question and reasoning that would justify [12] as the answer.
The question is: Janet bought some muffins at the bakery. Each muffin is 75 cents. Janet paid $20 and got $11 in change back. How many muffins did Janet buy?
Reasoning: Janet paid with $20 and got back $11, so her muffins cost $20 - $11 = $9. Each muffin cost 75 cents, so she bought 9 / .75 = 12 muffins.

Come up with a question and reasoning that would justify [3] as the answer.
The question is: Baseball season opened up with the Chicago Cubs at home at Wrigley Field. They scored 2 home runs in the third inning, 1 home run in the fifth inning and 2 more home runs in the eighth inning. Their opponents, the Cardinals, scored 1 home run in the second inning and 1 home run in the fifth inning. How many more home runs did the Chicago Cubs score than the Cardinals in the game?
Reasoning: The Chicago Cubs scored 2 home runs in the third inning, 1 home run in the fifth inning, and 2 home runs in the eighth for a combined total of 2 + 1 + 2 = 5 home runs for the game. The Cardinals scored 1 home run in the second inning and 1 home run in the fifth inning for a combined total of 1 + 1 = 2 home runs for the game. If the Chicago Cubs scored a total of 5 home runs in the game and the Cardinals scored a total of 2 home runs in the games then 5 - 2 = 3 more home runs were scored by the Chicago Cubs than the Cardinals in the game.

Come up with a question and reasoning that would justify [600] as the answer.
The question is: There are two warehouses. The first warehouse has twice as many boxes as the second warehouse. If the first warehouse has 400 boxes, how many boxes are there in both warehouses combined?
Reasoning: The second warehouse has 400 / 2 = 200 boxes. Collectively, there are 400 + 200 = 600 boxes in the first and second warehouse.
