[Question]Helen cuts her lawn starting in March and finishes in October. Her lawn mower uses 2 gallons of gas every 4th time she cuts her lawn. For March, April, September and October, she only cuts her law 2 times per month. In May, June, July and August, she has to cut her lawn 4 times per month. How many gallons of gas will she need to cut her lawn from March through October?
[Answer]For March, April, September and October, she cuts her lawn 2 a month. There are 4 months so she cuts her yard 2 * 4 = 8 times. For May, June, July and August, she cuts her lawn 4 times a month. There are 4 months so she cuts her yard 4 * 4 = 16 times. During the entire 8 month period, she cuts her lawn 8 + 16 = 24 times. Every 4th time she cuts, she needs 2 gallons of gas. If she cuts her lawn 24 times a year then she needs to fill up 24 / 4 = 6 times. Each time she fills up, it takes 2 gallons of gas so 2 * 6 = 12 gallons of gas per year. The answer is 12.
Q: Otto's local kitchen supply store charges $5.00 for the first knife that you need sharpened. They charge $4.00 for the next 3 knives and $3.00 for any knife after that. If Otto has 9 knives that need to be sharpened, how much will it cost to sharpen his knives?
A: Knives 2, 3 & 4 will cost $4.00 each to sharpen so that's 3 * 4 = $12.00. Knives 5 - 9 will cost $3.00 each to sharpen so that's 5 * 3 = $15.00. The first knife will cost $5.00, the next 3 cost $12.00 and the rest cost $15.00 for a total of 5 + 12 + 15 = $32.00. The answer is 32.
Question: Carly is thinking about buying a wallet that costs $22 and a purse that costs $3 less than four times the cost of the wallet. What is the combined cost of both items?
Answer: First quadruple the price of the wallet: $22 * 4 = $88. Then subtract $3 to find the cost of the purse: $88 - $3 = $85. Then add the price of the wallet and purse to find the total cost: $85 + $22 = $107. The answer is 107.
[Question]A football club has a balance of $100 million. The club then sells 2 of its players at $10 million each, and buys 4 more at $15 million each. How much money is left in the club register in millions of dollars?
[Answer]The 2 players are sold for a total of 2 * 10 = $20 million. So the club has 100 + 20 = $120 million. The cost of buying 4 more players at $15 million each is 4 * 15 = $60 million. So the club now has 120 60 = $60 million. The answer is 60.

Question: Jeanine bought 18 pencils and Clare bought half as many pencils. If Jeanine gave one third of his pencils to Abby, how many more pencils than Clare does Jeanine have now?
Answer:
Clare bought half of 18 pencils which is 18 / 2 = 9 pencils. One - third of 18 pencils is (1 / 3) * 18 = 6 pencils. Jeanine gave out 6 pencils so he has 18 - 6 = 12 pencils left. Jeanine now has 12 - 9 = 3 pencils. The answer is 3.
