Question: Zara bought 24 cows, 7 sheep, and some goats. Next week, she will transport all of them to a new farm in 3 equally-sized groups of 48 animals per group. How many goats does she own?
Answer: Zara will transport a total of 3 * 48 = 144 animals. The known number of animals is 24 + 7 = 31 cows and sheep. Zara therefore has 144 - 31 = 113 goats. The answer is 113.
[Question]An air conditioner running for eight hours would consume 7.2 kilowatts. How many kilowatts would the air conditioner consume if it was used for 6 hours a day for 5 days?
[Answer]The air conditioner consumes 7.2 / 8 = 0.9 kilowatt per hour. So, in 6 hours, it will consume 0.9 kilowatts per hour * 6 hours = 5.4 kilowatts. In 5 days, its total consumption is 5.4 kilowatts * 5 = 27 kilowatts. The answer is 27.
Q: Michael is baking a cake and needs 6 cups of flour. The only measuring cup he has is the 1/4 cup. He has an 8 cup bag of flour and realizes it would be faster to measure the flour he doesn't need, take it out of the bag, and then dump the rest of the bag into the bowl. How many scoops should he remove?
A: He needs to remove 2 cups of flour because 8 minus 6 equals 2. He needs to use 8 scoops because 2 divided by .25 equals 8. The answer is 8.
Question: In a shopping mall, one T-shirt costs $20 each; a pair of pants costs $80; a pair of shoes costs $150. All items will get a 10% discount. How much does Eugene have to pay if he buys four T-shirts, three pairs of pants, and two pairs of shoes?
Answer: The total cost of the four T - shirts is 4 x $20 = $80. Three pairs of pants cost 3 x $80 = $240. Two pairs of shoes cost 2 x $150 = $300. The total amount of all the items is $80 + $240 + $300 = $620. Thus, Eugene will get a discount of 10 / 100 x $620 = $62. Therefore, Eugene will have to pay $620 - $62 = $558. The answer is 558.
Q: 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?
A:
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.
