Come up with a question and reasoning that would justify [1200] as the answer.
The question is: Braden had $400 in his money box. He had also placed a bet today with Byan that the Raptors will beat the Bulls. If the game's outcome was as Braden predicted, and he and Bryan had agreed to give the winner twice as much money as Braden had in his money box, calculate the total amount of money Braden had in his money box after winning the bet?
Reasoning: If they agreed to give the winner twice as much money as Braden had in his money box, after winning the bet, Braden received 2 * $400 = $800. Braden increased the total amount of money in his money box to $800 + $400 = $1200.

Come up with a question and reasoning that would justify [12] as the answer.
The question is: John buys game loot boxes for $5 each. The average value of items inside is $3.5.  He spends $40 on loot boxes. What is the average amount he lost?
Reasoning: He bought 40 / 5 = 8 boxes. He loses an average of 5 - 3.5 = $1.50 per box. So he loses an average of 1.5 * 8 = $12.

Come up with a question and reasoning that would justify [21] as the answer.
The question is: George bought some food for his trip: a bottle of juice, a sandwich, and a bottle of milk. The sandwich was for $4, and the juice was two times more expensive. The bottle of milk cost was 75% of the total cost of the sandwich and juice. How much did George pay for his food?
Reasoning: The juice was two times more expensive than the sandwich, so it was 4 * 2 = $8. The juice and the sandwich in total were a cost of 4 + 8 = $12. So the cost of one bottle of milk was 75 / 100 * 12 = $9. In total for all the food, George paid 12 + 9 = $21.
