Come up with a question and reasoning that would justify [160] as the answer.
The question is: Together 3 friends watched 411 short videos. Kelsey watched 43 more than Ekon. Ekon watched 17 less than Uma. How many videos did Kelsey watch?
Reasoning: Let U = the number of videos Uma watched. Ekon = U - 17. Kelsey = (U - 17) + 43 = U + 26. U + U - 17 + U + 26 = 411. 3U + 9 = 411. 3U = 402. U = 134. Kelsey = 134 + 26 = 160 videos. Kelsey watched 160 videos.

Come up with a question and reasoning that would justify [12] as the answer.
The question is: For every 5 people that attend a poetry class, the teacher gives one of the students a lollipop. If 45 people show up for class, then another 15 come in a while later, how many lollipops did the teacher give away?

The question is: In mid-May, the river flowing through Moreland is five feet deep. By mid-June, the river is 10 feet deeper than mid-May. By mid-July, the river is three times deeper than mid-June. How many feet deep is the river by mid-July?
Reasoning: In mid - June, the river is 5 + 10 = 15 feet deep. In mid - July, the river is 15 * 3 = 45 feet deep.
