[Question]Mr. Roper cuts his lawn 15 days a month beginning in April and ending in September. From October to the end of March he cuts his lawn three times a month. What is the average number of times that Mr. Roper cuts his yard per month?
[Answer]For 6 months of the year he cuts his yard 15 days per month so he cuts his yard 6 * 15 = 90 times. For the remaining 6 months of the year, he cuts his yard three times a month so he cuts his yard 6 * 3 = 18 times. He cuts his yard 90 times for part of the year and 18 times for the rest of the year for a total of 90 + 18 = 108 times. There are 12 months in a year and he cuts his yard 108 times so he averages 108 / 12 = 9 times per month. The answer is 9.
Q: Nancy bought a pie sliced it into 8 pieces. She gave 1/2 to Joe and Darcy, and she gave 1/4 to Carl. How many slices were left?
A: The total number of slices she gave to Joe and Darcy is 1 / 2 x 8 = 4. The total slice she gave to Carl is 1 / 4 x 8 = 2. Therefore, the total slices left is 8 - 4 - 2 = 2. The answer is 2.
Question: Monica and Sheila are twins. Their mother gave them $50 and told them to buy some toilet paper and spend the remainder on groceries. The toilet paper cost $12. They bought apples, butter, eggs, and a large ham for twice the cost of the toilet paper. Since they still had some leftover money, they called their mother and she gave them permission to buy whatever they wanted for themselves as long as they shared the money evenly. They saw some boots they really liked, but a pair of boots costs 3 times the amount they had left. How much more would Monica and Sheila each have to add of their own money to buy two pairs of boots?
Answer: The groceries cost $12 x 2 = $24. Including the toilet paper, Monica and Sheila had already spent $12 + $24 = $36. This means that they had $50 - $36 = $14 left to spend on themselves. However, the boots cost $14 x 3 = $42 per pair. Two pairs of boots would cost $42 x 2 = $84. They need another $84 - $14 = $70 to buy two pairs. Each of them needs to add another $70 / 2 = $35. The answer is 35.
[Question]Aubrey has a deck of cards with 52 cards in it. She then adds two additional cards to the deck. If she splits the deck evenly among herself and two other players, how many cards does each player have?
[Answer]The deck has 54 cards because 52 + 2 = 54. There are three players because 1 + 2 = 3. Each player gets 18 cards because 54 / 3 = 18. The answer is 18.
Q: A pack of dogs found a pile of bones in the dumpster behind the butcher shop. One by one, the dogs crawled into the dumpster, grabbed a mouthful of bones, and ran off with their newfound treasure. In all, there were 5 dogs. The first dog carried off 3 bones. The second dog carried off 1 less bone than the first dog. The third dog carried off twice as many as the second dog. The fourth dog carried off one bone, and the fifth dog carried off twice the number of bones as the fourth dog carried, leaving no remaining bones in the dumpster. How many bones were in the original pile of bones?
A: The second dog carried off 1 less bone than the first dog, or 3 - 1 = 2 bones. The third dog carried off twice as many bones as the third dog, or 2 * 2 = 4 bones. The fifth dog carried off twice the number of bones as the fourth dog carried, or 2 * 1 = 2 bones. Therefore, the original pile of bones contained 3 + 2 + 4 + 1 + 2 = 12 bones. The answer is 12.

Lionel = 4 * 5280 = 21120 feet. Esther = 975 * 3 = 2925 feet. Together = 21120 + 2925 + 1287 = 25332 feet. Together the friends walked 25332 feet. The answer is 25332.
