[Question]1,800 fish swim westward, 3,200 swim eastward, and 500 swim north. What is the number of fish left in the sea, if fishers catch 2/5 of the fish that swam eastward and 3/4 of the fish that swam westward?
[Answer]When fishers caught 3 / 4 of the fish that swam westward, their total number reduced by 3 / 4 * 1800 fish = 1350. The total number of fish that remained from the total number that swam eastward is 1800 fish - 1350 fish = 450 fish. If fishers caught 2 / 5 of the fish that swam eastward, their total number reduced by 2 / 5 * 3200 fish = 1280 fish. 3200 fish - 1280 fish = 1920 fish remained in the sea from the number that swam westward. The total number of fish in the sea after fishers caught some is 500 of the number that went north + 450 of the fish that swam westward + 1920 of the fish that swam eastward = 2870 fish. The answer is 2870.
Q: A baker has 10 cheesecakes on the display while 15 more are still in the fridge. If the baker has sold 7 cheesecakes from the display, how many more cheesecakes are left to be sold?
A: A baker has a total of 10 + 15 = 25 cheesecakes both from the display and the fridge. Therefore, there are 25 - 7 = 18 more cheesecakes to be sold. The answer is 18.
Question: Bianca worked for 12.5 hours last weekend. Celeste worked for twice that amount of time and McClain worked 8.5 hours less than Celeste. How many minutes did the 3 people work in total?
Answer: Bianca = 12.5 hours. Celeste 2 * 12.5 = 25 hours. McClain = 25 - 8.5 = 16.5 hours. Total + 12.5 + 25 + 16.5 = 54 hours. 54 hours * 60 minutes = 3240 minutes. Bianca, Celeste and McClain worked a total of 3240 minutes last weekend. The answer is 3240.
[Question]Hector purchased a container of gumballs. He gave 4 to Todd, then he gave twice as many as he had given Todd to Alisha, and then he gave 5 less than four times as many to Bobby as he had given to Alisha. If Hector had 6 gumballs remaining, what is the total number of gumballs that Hector purchased?
[Answer]Hector gave to Alisha twice as many as he had given Todd, for a total of 4 * 2 = 8 gumballs,. Hector gave 5 less than four times as many to Bobby as he had given to Alisha, or a total of (8 * 4) - 5 = 27 gumballs. If Hector had 6 gumballs remaining, he originally purchased 4 + 8 + 27 + 6 = 45 gumballs. The answer is 45.
Q: Steve wanted to make a total of $100 within four days, so he took on a berry-picking job in Sweden. The job paid $2 for every pound of lingonberries picked. On Monday he picked 8 pounds. Tuesday’s harvest was triple what he had picked the previous day. On Wednesday he felt very tired and decided to rest. How many pounds of lingonberries did Steve have to pick on Thursday?
A: On Monday, Steve was paid 8 * 2 = 16 dollars. Tuesday’s harvest was 3 * 8 = 24 pounds. The 24 pounds Steve picked on Tuesday gave him 24 * 2 = 48 dollars. So, the amount Steve earned from the first two days on the job is 16 + 48 = 64 dollars. Since Steve rested on Wednesday, he made 0 dollars, meaning his earnings were 64 + 0 = 64 dollars. The difference between Steve’s earnings and his target is 100 - 64 = 36 dollars. Since he was paid 2 dollars for each pound of lingonberries, Steve needed to pick 36 / 2 = 18 pounds. The answer is 18.
Question: Gary is buying chlorine for his rectangular pool, which is 10 feet long, 8 feet wide, and 6 feet deep. Gary needs to buy one quart of chlorine for every 120 cubic feet of water in his pool. If chlorine costs $3 a quart, how much does Gary spend on chlorine?
Answer:
First find the volume of the pool by multiplying the length by the width by the height: 10 ft * 8 ft * 6 ft = 480 cubic feet. Then divide the volume of the pool by the number of cubic feet one quart of chlorine can sterilize: 480 cubic feet / 120 cubic feet / quart = 4 quarts. Then multiply the number of quarts Gary needs to buy by the price per quart to find out how much money he spends: $3 / quart * 4 quarts = $12. The answer is 12.
