[Question]Ben has $2000 for his business operations costs. He orders goods from his supplier and writes them a cheque for $600. His debtor pays him $800 from the purchases they had made on credit. Mr. Ben then decides to do equipment maintenance and spends $1200 on the whole operation. How much money is Mr. Ben remaining with?
[Answer]When Mr. Ben writes the cheque, he remains with $2000 - $600 = $1400. His debtor pays him $800, increasing his operation capital to $1400 + $800 = $2200. He spends $1200, remaining $2200 - $1200 = $1000 for business operations cost after maintenance. The answer is 1000.

[Question]Cary is saving money to buy a new pair of shoes that cost $120. He has already saved $30. He earns $5 for every lawn he mows. If he mows 3 lawns each weekend, how many more weekends will he have to mow lawns before he can afford to buy the shoes?
[Answer]Cary needs to save an additional $120 - $30 = $90. Cary makes $5 * 3 = $15 each weekend. It will take 90 / 15 = 6 more weekends to save enough money to afford the shoes. The answer is 6.

[Question]Carmen is preparing dinner plates for a row of customers at the counter in a diner. She likes to put a couple of sprigs of parsley on each plate for decoration. However, she is very low on parsley and doesn't have enough to even put 1 sprig on every plate, so she needs to break several of the parsley sprigs in two to make 2 smaller ones to stretch them out. If she decorates 8 plates with one whole parsley sprig and 12 plates with 1/2 a sprig each, how many sprigs of parsley does she have left if she started with 25?
[Answer]Carmen decorates 8 plates with 1 whole sprig of parsley, 8 plates x 1 parsley sprig each = 8 parsley sprigs. She also decorates 12 plates with 1 / 2 a sprig each, 12 x 1 / 2 = 6 parsley sprigs. She started with 25 parsley sprigs and has used 8 + 6 = 14 parsley sprigs. After using 14 parsley sprigs, she has 25 - 14 = 11 sprigs left. The answer is 11.

[Question]Conner has a dune buggy that he rides in the desert. On flat sand, it can ride at a speed of 60 miles per hour. When traveling on downhill slopes, it can race at 12 miles per hour faster than it can when it is on flat sand. And when riding on an uphill inclined slow, it travels at a speed 18 miles per hour slower than when it is riding on flat sand. If Conner rides his dune buggy one-third of the time on flat sand, one-third of the time on uphill slopes, and one-third of the time on downhill slopes, what is his average speed in miles per hour?
[Answer]
12 mph faster than 60mph is 60 + 12 = 72 mph. 18 mph slower than 60 mph is 60 - 18 = 42 mph. If he spends 1 / 3 of the time at each of these three speeds, then he averages (60 + 72 + 42) / 3 = 58 mph. The answer is 58.
