Come up with a question and reasoning that would justify [16] as the answer.
The question is: Camila has only gone hiking 7 times in her life. Amanda has gone on 8 times as many hikes as Camila, and Steven has gone on 15 more hikes than Amanda. If Camila wants to say that she has hiked as many times as Steven and plans to go on 4 hikes a week, how many weeks would it take Camila to achieve her goal?
Reasoning: Amanda has gone on 7 hikes x 8 = 56 hikes. Steven has gone on 56 hikes + 15 hikes = 71 hikes. Camila needs to go on another 71 hikes - 7 hikes = 64 hikes. Camila will achieve her goal in 64 hikes / 4 hikes / week = 16 weeks.

Come up with a question and reasoning that would justify [2] as the answer.
The question is: There are 30 students in Ms. Leech's class. Twice as many girls as boys are in the class. There are 10 boys in the class and each boy today brought 5 cups for science activity class as Ms. Leech had instructed. If the total number of cups brought by the students in the class is 90, how many cups did each girl bring?
Reasoning: If there are 30 students in Ms. Leech's class, and the number of boys is 10, the number of girls in Ms. Leech class is 30 - 10 = 20. If each boy brought 5 cups for the science activity, the total number of cups brought by the boys is 5 * 10 = 50 cups. The number of cups that the girls brought is 90 - 50 = 40 of the total number. Since the number of girls in the class is 20, each girl brought 40 / 20 = 2 cups each.

Come up with a question and reasoning that would justify [91] as the answer.
The question is: There are 32 tables in a hall. Half the tables have 2 chairs each, 5 have 3 chairs each and the rest have 4 chairs each. How many chairs in total are in the hall?
Reasoning: Half of 32 tables is 32 * (1 / 2) = 16 tables. 16 tables have 2 chairs each for a total of 16 * 2 = 32 chairs. 5 tables have 3 chairs each for a total of 5 * 3 = 15 chairs. There are 32 - (16 + 5) = 11 tables left. 11 tables have 4 chairs each for a total of 11 * 4 = 44 chairs. The total number of chairs is 32 + 15 + 44 = 91 chairs.
