[Question]Josh gets together with 7 friends. Everyone including him puts 5 dollars into a pot. First place gets 80% of the money. Second and third place split the rest. How much money does third place get?
[Answer]7 + 1 = 8 people threw money into the pot. So the amount of money in the pot is 8 * 5 = $40. First place gets 40 * .8 = $32. So there is 40 - 32 = $8 left in the pot after first place gets his cut. So third place gets 8 / 2 = $4. The answer is 4.
Q: Edward had $17.80 to spend at the toy store. He bought 4 toy cars that cost $0.95 each and a race track that cost $6.00. How much money does Edward have left to buy more toys?
A: The cost of the toy cars is 4 × $0.95 = $3.80. The total cost of the toys is $3.80 + $6.00 = $9.80. Edward has $17.80 − $9.80 = $8.00 left. The answer is 8.
Question: There are twice as many centipedes as humans on a certain island and half as many sheep as humans. How many sheep and humans in total are on the island if the number of centipedes is 100?
Answer: The number of humans on the island is 100 / 2 = 50. There are 1 / 2 * 50 = 25 sheep on the island. The total number of sheep and humans is 25 + 50 = 75. The answer is 75.
[Question]A bag of dozen apples costs $14 and Brian has already spent $10 on kiwis and half that much on bananas. What's the maximum number of apples Brian can buy if he left his house with only $50 and needs to pay the $3.50 subway fare each way?
[Answer]Brian requires a total of $3.50 + $3.50 = $7 to pay for the round trip subway fare. We also know he has spent half (1 / 2) the amount he spent on kiwis on bananas, so he'll spend (1 / 2) * $10 = $5 on bananas. So far in total he has spent $7 for his subway fare + $5 on bananas + $10 on kiwis = $7 + $5 + $10 = $22. If he left his house with only $50, then all he will have left for apples would be $50 - $22 = $28. If a bag of apples costs $14, then Brian would only be able to buy a maximum of $28 / $14 = 2 bags of apples. If each bag of apples has a dozen (12) apples, then (2) two bags will have 12 * 2 = 24 apples. The answer is 24.
Q: Allison, a YouTuber, uploads 10 one-hour videos of food reviews each day to her channel. She uploaded videos halfway through June, at that pace, and then doubled the number of video hours she uploaded on the remaining days. What's the total number of video hours she has uploaded at the end of the month?
A: Since June has 30 days, halfway is 1 / 2 * 30 = 15. The total number of video hours halfway through June is 10 * 15 = 150. When she doubled the number of video hours, the total per day became 10 * 2 = 20. The total number of video hours for the remaining days is 15 * 20 = 300. The total number of video hours for the whole month is 300 + 150 = 450. The answer is 450.
Question: Tanya went to the grocery store to buy some fruit. She bought 6 pears, 4 Granny Smith apples, 2 pineapples, and a small basket of plums, which were all placed in a single paper bag. Unfortunately, the bag that the fruit had been placed in had developed a hole. Therefore, as Tanya walked home, half of the fruit fell out of the bag. When she later counted the fruit left in the bag, there were only 9 pieces remaining. How many plums did she buy?
Answer:
If half of the fruit equals 9 pieces, then Tanya bought 2 * 9 = 18 pieces of fruit. Thus, Tanya bought 18 - 6 - 4 - 2 = 6 plums. The answer is 6.
