[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.
So the answer is 1000.

[Question]: The chicken crossed the road to get to the other side twice for the thrill of it. The first time, it had to dodge 23 speeding cars. The second time, a person tried to catch it and accidentally pulled out twice as many feathers as the number of cars the chicken had dodged. The chicken had 5263 feathers before its thrill-seeking road crossings. How many feathers did it have afterward?
[Answer]: The chicken lost 23 * 2 = 46 feathers on its second road crossing. Thus, it had 5263 - 46 = 5217 feathers after crossing the road twice.
So the answer is 5217.

[Question]: Simon wanted to buy flowers that his mom could plant for Mother's Day. The garden center was offering 10% off all purchases. He bought 5 pansies at $2.50 each, one hydrangea that cost $12.50 and 5 petunias that cost $1.00 each. If he paid with a $50 bill, how much change would Simon receive back from his purchase?
[Answer]:
5 pansies at $2.50 each is 5 * 2.50 = $12.50. 5 petunias at $1.00 each 5 * 1 = $5.00. All total he spends 12.50 + 12.50 + 5.00 = $30.00. The sale is 10% off so 30 * .10 = $3.00. The purchase total now comes to 30 - 3 = $27.00. He pays with a $50 bill so 50 - 27 = $23.00.
So the answer is 23.
