Question: Mr. Lu owns a computer store. For last month, half of their sales are laptops, one-third are netbooks, and the rest are desktop computers. If Mr. Lu's store was able to sell a total of 72 computers, how many of them are desktop computers?
Answer: There were 72 / 2 = 36 laptops sold. There were 72 / 3 = 24 netbooks sold. So, there were a total of 36 + 24 = 60 laptops and netbooks sold. Thus, 72 - 60 = 12 desktop computers were sold last month. The answer is 12.

Q: There are 40 more buyers in the grocery store today than yesterday. There were half the number of buyers yesterday as there were the day before, and the day before had 50 buyers. Nobody visited the store on more than one day. What's the total number of buyers who've visited the store in the three days?
A: If yesterday the number of buyers was half the number of buyers the day before, then yesterday there were 1 / 2 * 50 = 25 buyers. Today has 40 more buyers than yesterday, so there were 40 + 25 = 65 buyers today. The total number of buyers in the store for the three days will be 65 + 25 + 50 = 140 buyers. The answer is 140.
Question: Mr. Shaefer harvested 500 lychees in a carton and took them to the market. He sold half of them and took home the remaining number of lychees where they ate 3/5 of them. Calculate the number of lychees remaining.
Answer: At the market, Mr. Shaefer sold half of the lychees, which is 1 / 2 * 500 = 250. The remaining number of lychees is 500 - 250 = 250. At home, they ate 3 / 5 * 250 = 150 lychees. The total number of lychees remaining is 250 - 150 = 100. The answer is 100.
Q: Yulia was able to net $44 in profit this week. Her lemonade stand made a gross revenue of $47 this week. She was also able to babysit and made $31. However, her lemonade stand is expensive to run because she needs to buy lemons, sugar, and sunscreen. How much did she spend to operate her lemonade stand, in dollars?
A:
Yulia's total gross revenue was $47 + $31 = $78. To calculate her overhead we must subtract her total profit from her gross revenue which is $78 - $44 = $34. The answer is 34.
