Come up with a question and reasoning that would justify [585] as the answer.
The question is: It's payday but Jebb has to pay 10% for the tax. If his pay is $650, how much is his take-home pay?
Reasoning: Jebb has to pay $650 x 10 / 100 = $65. Therefore, Jebb's take - home pay is $650 - $65 = $585.

Come up with a question and reasoning that would justify [4] as the answer.
The question is: In the class of 24 students, half are doing silent reading, and a third are playing board games. The rest are catching up on homework. How many students are catching up on homework?
Reasoning: 24 / 2 = 12 students are doing silent reading. 24 / 3 = 8 students are playing board games. So 12 + 8 = 20 students are accounted for. Then 24 - 20 = 4 students are catching up on homework.

Come up with a question and reasoning that would justify [134400] as the answer.
The question is: Roberto recently received a 20% raise from his previous salary, which was already 40% higher than his starting salary. If Roberto's starting salary was $80,000, what is his current salary?
Reasoning: Roberto has received 2 raises. On his first raise he received a 40% bump, therefore his new salary was $80,000 * 140% = $112,000. On his second raise, Roberto received a 20% bump, therefore his current salary is $112,000 * 120% = $134,400.
