Question: Jake is watching a new show, and is worried about how much time he has spent watching it. He spent half the day on Monday watching his show, 4 hours on Tuesday watching his show, a quarter of the day on Wednesday watching his show, and he spent half as much time watching the show on Thursday as he had done in total throughout the previous few days. On Friday, he finally finished watching it. If the entire show is 52 hours long, how many hours did Jake watch on Friday?
Answer: On Monday, Jake watched 24 hours / 2 = 12 hours. On Wednesday, he watched 24 hours / 4 = 6 hours. So from Monday to Wednesday, he watched a total of 12 Monday hours + 4 Tuesday hours + 6 Wednesday hours = 22 hours. He watched half of this on Thursday, which is 22 hours / 2 = 11 hours. So from Monday to Thursday, he watched 22 + 11 = 33 hours. To finish the show on Friday, he must have therefore watched 52 – 33 = 19 hours. The answer is 19.

Question: Chris wanted to buy a new video game that costs $60 as well as an assortment of candy that costs $5. To earn the money, he agreed to babysit his little sister for $8 per hour. If he works 9 hours, how much money will be left over after he makes his purchases?
Answer: He wants to buy a $60 game and $5 of candy so 60 + 5 = $65. He will make $8 per hour of babysitting and will work 9 hours so 8 * 9 = $72. He made $72 and spent $65 so 72 - 65 = $7 left over. The answer is 7.
[Question]John assembles computers and sells prebuilt computers as a business. The parts for the computer cost $800. He sells the computers for 1.4 times the value of the components. He manages to build 60 computers a month. He has to pay $5000 a month in rent and another $3000 in non-rent extra expenses a month. How much profit does he make a month?
[Answer]He sells each computer for 1.4 * 800 = $1120. That means he makes a profit of 1120 - 800 = $320 per computer. So he makes 320 * 60 = $19200 from selling computers. He has extra expenses of 5000 + 3000 = $8000 a month. So his profit is 19200 - 8000 = $11,200. The answer is 11200.
[Question]Andy harvests all the tomatoes from 18 plants that have 7 tomatoes each. If he dries half the tomatoes and turns a third of the remainder into marinara sauce, how many tomatoes are left?
[Answer]
First find the total number of tomatoes harvested: 18 plants * 7 tomatoes / plant = 126 tomatoes. Then divide that number by 2 to find how many tomatoes are left undried: 126 tomatoes / 2 = 63 tomatoes. Then divide that number by 3 to find how many tomatoes are turned into sauce: 63 tomatoes / 3 = 21 tomatoes. Then subtract that number from the number of undried tomatoes to find the remaining number of tomatoes: 63 tomatoes - 21 tomatoes = 42 tomatoes. The answer is 42.
