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: 60

Reasoning and 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: 120
