[Question]Bill is stocking the kitchenware section of the Walmart. He needs to stack 60 pots. On each shelf, he can stack five pots vertically and three sets of vertically stacked pots side-by-side. How many shelves does he need to stock all the pots?
[Answer]First find how many pots fit on one shelf: 5 pots / set * 3 sets = 15 pots. Then divide the number of pots Bill has by the number that fit on each shelf: 60 pots / 15 pots / shelf = 4 shelves. The answer is 4.

[Question]To pass the time while she is waiting somewhere Carla likes to count things around her. While she is waiting for school to start on Monday she counts the tiles on the ceiling--38. While she is waiting for everyone to finish their tests after she has handed in hers, she counts the books in the room--75. On Tuesday Carla counts all the tiles twice in a row and she counts the books three times in a row when she has to wait for a long time for the teacher to finish handing out the graded tests. If every time Carla counts something counts as once, how many times has Carla counted something on Tuesday?
[Answer]When Carla was waiting on Monday she counted 38 ceiling tiles and on Tuesday she counted them twice, 38 ceiling tiles x 2 = 76 times she counted a ceiling tile. She also counted 75 books in the room on Monday and counted them three times in a row on Tuesday, 75 books x 3 = 225 times she counted a book. On Tuesday Carla counted the ceiling tiles 76 times + counted books 225 times = 301 times Carla counted something on Tuesday. The answer is 301.

[Question]Sarah decided to pull weeds from her garden. On Tuesday she pulled 25 weeds. The next day she pulled three times the number of weeds she did the day before. On Thursday her allergies bothered her and she could only pull up one-fifth of the weeds she pulled on the day before. Finally, on Friday it rained for half the day and she managed to pull up 10 fewer weeds than she did on Thursday. In total, how many weeds did she pull up?
[Answer]On Wednesday she pulled 25 * 3 = 75 weeds. On Thursday she pulled 75 / 5 = 15 weeds. On Friday she pulled 15 - 10 = 5 weeds. In total she pulled 25 + 75 + 15 + 5 = 120 weeds. The answer is 120.
