Q: James spends 10 minutes downloading a game, half as long installing it, and triple that combined amount of time going through the tutorial. How long does it take before he can play the main game?
A: First divide the download time in half to find the install time: 10 minutes / 2 = 5 minutes. Then add that amount of time to the download time: 5 minutes + 10 minutes = 15 minutes. Then triple that amount of time to find the tutorial time: 15 minutes * 3 = 45 minutes. Then add that time to the install and downtime time to find the total time: 45 minutes + 15 minutes = 60 minutes. The answer is 60.
Question: John has to replace the ball bearings for machines he works with. He has 10 machines and they take 30 ball bearings each. It normally costs $1 per ball bearing but right now there is a sale where they are only $.75. Also since he is buying in bulk he gets a further 20% discount. How much money did he save by buying them all during the sale rather than 1 at a time?
Answer: He needs to replace 30 * 10 = 300 ball bearings. The normal price is 300 * 1 = $300. Because of the sale he only has to pay 300 * .75 = $225. He then gets a discount which shaves another 225 * .2 = $45 off the price. That means he only pays 225 - 45 = $180. So he saved 300 - 180 = $120. The answer is 120.
Q: Tim gets 6 hours of sleep 2 days in a row. To make up for it he sleeps 10 hours the next 2 days. How much sleep did he get?
