Come up with a question and reasoning that would justify [18] as the answer.
The question is: Oliver is working out in a gym. On Monday he worked out for 4 hours, and the next day for 2 hours less. On Wednesday he decided to work out twice as much as on Monday. On Thursday the gym was closed, so Oliver needed to exercise at home which took twice as much time as on Tuesday. How many hours in total have Oliver worked out during these four days?
Reasoning: On Tuesday, Oliver worked out for 4 - 2 = 2 hours. On Wednesday he decided to work out twice as much as on Monday, so for 2 * 4 = 8 hours. On Thursday, at home, Oliver trained twice as much as on Tuesday, so for 2 * 2 = 4 hours. In total Oliver trained for 4 + 2 + 8 + 4 = 18 hours.

Come up with a question and reasoning that would justify [35] as the answer.
The question is: Jonas is trying to expand his wardrobe. He has 20 pairs of socks, 5 pairs of shoes, 10 pairs of pants and 10 t-shirts. How many pairs of socks does he need to buy to double the number of individual items in his wardrobe?
Reasoning: First, we must recognize that all pairs of shoes and socks are actually two items each, whereas the pants and the t - shirts are individual items. Therefore there are 20 * 2 = 40 individual socks in 20 pairs of socks. Similarly, there are 5 * 2 = 10 individual shoes in 5 pairs of shoes. Therefore, Jonas has 40 + 10 + 10 + 10 = 70 individual items in his collection. To double this number, we perform 70 * 2 = 140. This means we need 140 - 70 = 70 new items to double the size. Since there are 2 individual socks in each pair, we take 70 / 2 = 35 new pairs of socks.

Come up with a question and reasoning that would justify [14] as the answer.
The question is: Whitney's mom gave her two $20 bills to spend at the school book fair. Whitney has decided to buy 2 posters, 3 notebooks, and 2 bookmarks. Each poster costs $5, each notebook costs $4, and each bookmark costs $2. How much money, in dollars, will Whitney have left over after the purchase?
Reasoning: Whitney is buying 2 posters for $5 each, so the posters will cost 2 * $5 = $10 total cost for posters. Whitney is buying 3 notebooks for $4 each, so the notebooks will cost 3 * $4 = $12 total cost for notebooks. Whitney is buying 2 notebooks for $2, so the bookmarks 2 * $2 = $4 total cost for bookmarks. Since Whitney is paying $10 for posters, $12 for notebooks, and $4 for bookmarks, her total purchase will cost $10 + $12 + $4 = $26 total purchase cost. Whitney's mom gave her 2 $20 bills, so she will be paying with 2 * $20 = $40 total payment. Since Whitney is paying with $40 and her purchase cost will be $26, she will have $40 - $26 = $14 left over after the purchase.
