Come up with a question and reasoning that would justify [23] as the answer.
The question is: A papaya tree will grow 2 feet in the first year. In the second year, it will grow 50% more than the first year. In the third year, the tree will grow 50% more than in the second year. In the fourth year, it will grow twice as much as the third year. In the fifth year, it will grow half as much as the fourth year. When the tree is 5 years old, how tall is the tree?
Reasoning: In the second year, the tree will grow 2 x 1.5 = 3 feet. In the third year, it will grow 3 x 1.5 = 4.5 feet. In the fourth year, it will grow 4.5 x 2 = 9 feet. In the fifth year, it will grow 9 / 2 = 4.5 feet. When the tree is 5 years old, including the first year's growth, it will be this tall 2 + 3 + 4.5 + 9 + 4.5 = 23 feet.

Come up with a question and reasoning that would justify [2800] as the answer.
The question is: Jocelyn bought a car 3 years ago at $4000. If the car's value has reduced by 30%, calculate the current value of the car.
Reasoning: If Jocelyn bought the car 3 years ago at $4000, the car's value has reduced by 30 / 100 * $4000 = $1200. The current value of the car is $4000 - $1200 = $2800.

Come up with a question and reasoning that would justify [21600] as the answer.
The question is: An Italian restaurant earns $600 every weekday and twice as much on the weekend. How much money does it earn by the end of the month?
Reasoning: On weekdays it earns $600 / weekday * 5 weekdays = $3000. During the weekend it earns twice as much each day so it makes ($600 * 2) / weekend day * 2 weekend days = $2400. Every week it earns $3000 + $2400 = $5400. By the end of the month, it earns $5400 / week * 4 weeks = $21600.
