Question: 240 sixth-grade students were asked about the number of novels they read per month. 1/6 of students read three or more novels, 35% of students read two novels, 5/12 of students read one novel, and the rest of the students do not read anything. Calculate the number of students who do not read novels.
Answer: 1 / 6 * 240 students = 40 students. So 40 students read three or more novels. 35 / 100 * 240 students = 84 students. So 84 students read two novels. 5 / 12 * 240 students = 100 students. So 100 students read a novel. 240 students – (40 students + 84 students + 100 students) = 240 students – 224 students = 16 students. So 16 students don't read novels. The answer is 16.
[Question]Carl types at a speed of 50 words per minute. If he types continuously for 4 hours per day, how many words can he type in 7 days?

Question: James buys $3000 worth of stuff from Amazon. He has to return a TV that cost $700 and a bike that cost $500. He also sells another bike that cost 20% more than the bike he returned for 80% of what he bought it for. He then buys a toaster for $100. How much is he out of pocket for everything?
Answer: The items he returned were valued at $700 + $500 = $1200. So far he is out 3000 - 1200 = 1800 after recouping 1200. An item that is 20% more expensive cost 1 + .2 = 1.2 times as much as the item. So that means the bike he sold cost $500 * 1.2 = $600. He sold it for $600 * .8 = $480. From the bike that he had bought for 600, he was out 600 - 480 = 120. So far he is out 1800 + 120 = 1920. If he also bought a toaster worth 100, he was out 1920 + 100 = 2020. The answer is 2020.
