Come up with a question and reasoning that would justify [10] as the answer.
The question is: A coach placed 15 tennis balls and 5 soccer balls each into 5 baskets. He gave 5 of his students a short period of time to remove as many balls each from a basket as they could. 3 of them removed 8 balls each and the other 2 removed a certain number of balls each. If a total of 56 balls are still in the baskets, how many balls did the other 2 students each remove?
Reasoning: Combining the tennis and soccer balls, there are 15 + 5 = 20 balls in each basket. There are 5 baskets, hence 5 * 20 = 100 balls in total. 3 students removed 8 balls each, they removed 3 * 8 = 24 balls. From the total number of balls, they left 100 - 24 = 76 balls. There are 56 balls left so the other 2 students must have removed a total of 76 - 56 = 20 balls. This means that each of these 2 students removed 20 / 2 = 10 balls.

Come up with a question and reasoning that would justify [34] as the answer.
The question is: Three fifths of the light bulbs in the kitchen are broken. A third of the light bulbs in the foyer are also broken. If 10 light bulbs in the foyer are broken and there are 35 light bulbs in the kitchen, then how many light bulbs are not broken in both the foyer and kitchen?
Reasoning: There are 35 / 5 = 7 light bulbs to every fifth. 7 * 3 = 21 lightbulbs in the kitchen are broken. There are 35 - 21 = 14 light bulbs in the kitchen that are not broken. There are 10 * 3 = 30 light bulbs in the foyer in total. There are 30 - 10 = 20 light bulbs in the foyer that are not broken. There are 14 + 20 = 34 light bulbs that are not broken in both the foyer and kitchen.

Come up with a question and reasoning that would justify [165] as the answer.
The question is: A porcelain vase was originally priced at $200 but went on sale for 25% off. If Donna bought the porcelain vase and paid 10% sales tax, how much did she pay in total?
Reasoning: Donna got $200 x 25 / 100 = $50 less for the porcelain vase. So, the porcelain vase is now $200 - $50 = $150. Donna has to pay $150 x 10 / 100 = $15 for the sales tax. Therefore, she paid $150 + $15 = $165 in total.
