Come up with a question and reasoning that would justify [30] as the answer.
The question is: If Billy sleeps 6 hours one night, then 2 more hours than that the following night, and then half the previous amount the following night, and then finally triple the previous amount the final night, how much did he sleep in that four day period?
Reasoning: Billy slept 6 hours the first night. He then slept 6 + 2 = 8 hours the second night. Billy then slept 8 / 2 = 4 hours the third night. Finally, Billy slept 4 * 3 = 12 hours the fourth night. In total, Billy slept 6 + 8 + 4 + 12 = 30 hours.

Come up with a question and reasoning that would justify [21] as the answer.
The question is: Turner wants to ride the rollercoaster 3 times, the Catapult 2 times and the Ferris wheel once. It costs 4 tickets to ride the rollercoaster, 4 tickets to ride the Catapult and 1 ticket to ride the Ferris wheel. How many tickets does Turner need?
Reasoning: The number of tickets needed for the rollercoaster is 3 rides × 4 tickets / ride = 12 tickets. The number of tickets needed for the Catapult is 2 rides × 4 tickets / ride = 8 tickets. The number of tickets needed for the Ferris wheel is 1 ride × 1 ticket / ride = 1 ticket. Turner needs 12 tickets + 8 tickets + 1 tickets = 21 tickets.

Come up with a question and reasoning that would justify [108] as the answer.
The question is: On a road map, 1/4 inch represents 8 miles of actual road distance. The towns of Pence and Hillcrest are represented by points 3 3/8 inches apart on the map. What is the actual distance, in miles, between the towns?
Reasoning: If 1 / 4 inch on the map represents 8 miles on real land, 1 inch represents 4 * 8 = 32 miles. Since 1 inch represents 32 miles, 3 inches represent 3 * 32 = 96 miles. 1 / 4 inch represents 8 miles, 1 / 8 inch represents 8 / 2 = 4 miles because 1 / 8 is half of 1 / 4. If 1 / 8 inch represents 4 miles, 3 / 8 of an inch represents 3 * 4 = 12 miles. This means 3 3 / 8 inches on the map translate to 96 + 12 = 108 miles.
