Q: Cloud 9 Diving Company has taken individual bookings worth $12,000 and group bookings worth $16,000. Some people have cancelled at the last minute. $1600 has had to be returned to them. How much money has the sky diving company taken altogether?
A: Cloud 9 earned $12,000 + $16,000 = $28,000 from bookings. After returning money due to cancellations, they had a final total of $28,000 - $1600 = $26,400. The answer is 26400.
Question: Jason and Jeremy want to paint their wall white and agreed to split the cost of the paint. A gallon of paint costs $45 and can cover up to 400 square feet. How much will each of them contribute to the cost of the paint if their walls have a total area of 1600 square feet and will need a second coat?
Answer: They need 1600 square feet / 400 square feet / gallon = 4 gallons of paint for their walls. Since they will do a second coating, then they would need 4 gallons x 2 = 8 gallons in all. Eight gallons of paint will cost $45 / gallon x 8 gallons = $360. Thus, Jason and Jeremy will each contribute $360 / 2 = $180. The answer is 180.
[Question]In a town, there are four primary schools. Two of them can teach 400 students at a time, and the other two 340 students at a time. How many students at a time in total, can these four primary schools teach?
[Answer]Two schools can teach 400 students, so in total, they can teach 2 * 400 = 800 students. The other two schools can teach 340 students, which gives 2 * 340 = 680 students in total. So all four schools can teach 800 + 680 = 1480 students at a time. The answer is 1480.
Q: Jason is planning a parking garage that will have 12 floors. Every 3rd floor has a gate where drivers have to show ID, which takes two minutes. To get from one floor to the next, drivers have to drive 800 feet at 10 feet/second. How long, in seconds, does it take to get to the bottom of the garage from the top?
A: First find the total number of gates someone has to pass through: 12 floors / 3 floors / gate = 4 gates. Then find the total time someone spends waiting at the gates: 4 gates * 2 minutes / gate = 8 minutes. Then convert that time to seconds: 8 minutes * 60 seconds / minute = 480 seconds. Then find the time to drive through one floor in seconds: 800 feet / 10 feet / second = 80 seconds. Then multiply the time per floor by the number of floors to find the total driving time: 80 seconds / floor * 12 floors = 960 seconds. Then add the total driving time to the total time waiting at the gates to find the total time to get to the bottom: 960 seconds + 480 seconds = 1440 seconds. The answer is 1440.
Question: A math teacher had $100 to buy three different types of calculators. A basic calculator costs $8. A scientific calculator costs twice the price as the basic while a graphing calculator costs thrice the price as the scientific. How much change did she receive after buying those three different types of calculators?
Answer: A scientific calculator costs $8 x 2 = $16. A graphing calculator costs $16 x 3 = $48. So, she spent $8 + $16 + $48 = $72 for the three calculators. Therefore, the math teacher received $100 - $72 = $28 change. The answer is 28.
Q: John buys 3 barbells and gives $850 and gets $40 in change. How much did each barbell cost?

The total price of the barbells was 850 - 40 = $810. So each one cost 810 / 3 = $270. The answer is 270.
