Question: Grover bought 3 boxes of face masks. He plans to sell them for $0.50 each. If each box has 20 face masks, and he bought the 3 boxes for $15, how much will be his total profit?
Answer: Grover will earn $0.50 x 20 = $10 for each box. So, he will earn $10 x 3 = $30 after selling all the face masks. Therefore, his total profit will be $30 - $15 = $15. The answer is 15.
[Question]Jodi starts off walking 1 mile a day for 6 days a week. On the second week, she walks 2 miles a day, 6 days a week. On the third week, she walks 3 miles a day, 6 days a week. Finally on the fourth week, she walks 4 miles a day, 6 days a week. How many miles has she walked in 4 weeks?
[Answer]The first week she walked 1 mile, 6 days a week for a total of 1 * 6 = 6 miles. The second week she walked 2 miles, 6 days a week for a total of 2 * 6 = 12 miles. The third week she walked 3 miles, 6 days a week for a total of 3 * 6 = 18 miles. On the fourth week, she walked 4 miles, 6 days a week for a total of 4 * 6 = 24 miles. Over four weeks she has walked 6 + 12 + 18 + 24 = 60 miles. The answer is 60.
Q: At a CD store, 40% of the CDs cost $10 each, and the rest cost $5 each. Prince bought half the CDs sold at $10 each, and all of the CDs sold at $5 each. If the total number of CDs was 200, how much money did Prince spend on buying the CDs?
A: The number of CDs selling at $10 each at the store is 40 / 100 * 200 = 80. This means the store sells 200 - 80 = 120 CDs at $5 each. Prince bought 1 / 2 * 80 = 40 of the CDs selling at $10 each. The total amount of money Prince paid for the 40 CDs selling at $10 each is $40 * 10 = $400. If he bought all the CDs selling at $5 each, he paid a total of $5 * 120 = $600. For all the CDs he bought, Prince spent $600 + $400 = $1000. The answer is 1000.
Question: A group of 30 tourists sets out on a walking tour of the rainforest. Two tourists are eaten by anacondas, then half the remaining tourists try to pet poisonous dart frogs and get poisoned. If only 1/7 of the poisoned tourists recovered, how many tourists are left at the end of the tour?
Answer: First, subtract the two tourists the anacondas got from the initial 30 tourists: 30 - 2 = 28. Next, divide 28 by two to find out how many tourists got poisoned: 28 / 2 = 14. Now figure out how many of the 14 poisoned tourists recovered: 14 / 7 = 2. The total number of surviving tourists is 14 + 2 = 16. The answer is 16.
[Question]This evening in the nighttime sky over Texas, Mars can be seen until 12:10 AM. Jupiter does not appear until 2 hours and 41 minutes later, and Uranus does not appear until 3 hours and 16 minutes after Jupiter makes its first appearance. How many minutes after 6:00 AM does Uranus first appear in the evening sky over Texas this evening?
[Answer]Jupiter appears 2 hours and 41 minutes after 12:10 AM, which can be calculated in two parts;. 2 hours after 12:10 AM is 12:10 + 2:00 = 2:10 AM. And an additional 41 minutes after 2:10 AM is 2:10 + 0:41 = 2:51 AM. Uranus appears 3 hours and 16 minutes after 2:51 AM, which can be calculated in two parts:. 3 hours after 2:51 AM is 2:51 + 3:00 = 5:51 AM. And 16 minutes after 5:51 AM is 5:51 + 0:16 = 5:67 AM = 6:07 AM. Thus, 6:07 AM is 7 minutes after 6:00 AM. The answer is 7.
[Question]Harry wants to build a homemade helium balloon with his son, Kevin, so he and Kevin go to the store with $200. They buy a giant sheet to turn into a balloon for $42, a rope for $18, and a propane tank and burner for $14. They plan to use the rest of the money on helium. The helium is $1.50 per ounce. For every ounce they buy, the balloon can fly 113 feet higher. How many feet up can they fly the balloon?
[Answer]
They have $126 for helium because 200 - 42 - 18 - 14 = 126. They can buy 84 ounces of helium because 126 / 1.5 = 84. They can fly 9,492 feet up because 84 x 113 = 9,492. The answer is 9492.
