[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]James replaces the coffee for the household. There are 3 other people in the house and everyone drinks 2 cups of coffee a day. It takes .5 ounces of coffee per cup of coffee. If coffee costs $1.25 an ounce, how much does he spend on coffee a week?
[Answer]
There are 3 + 1 = 4 people in the house. So they drink 4 * 2 = 8 cups of coffee a day. That means they use 8 * .5 = 4 ounces of coffee a day. So they use 4 * 7 = 28 ounces of coffee a week. So he spends 28 * 1.25 = $35. The answer is 35.
