user: Q: At its current growth rate, a certain plant will be 80 feet tall after a year. If the plant grows at the same rate every month and is currently 20 feet tall, what's its monthly growth rate in feet?
A: If the plant is currently 20 feet tall, it will have grown by 80 - 20 = 60 feet after a year. Since a year has 12 months, and the tree grows at the same rate every month, the tree grows at 60 / 12 = 5 feet every month. The answer is 5.
Question: A ship left a port and headed due west, having 400 pounds of food for the journey's supply. After one day of sailing, 2/5 of the supplies had been used by the sailors in the ship. After another two days of sailing, the sailors used 3/5 of the remaining supplies. Calculate the number of supplies remaining in the ship to last the sailors until they dock.
Answer: After one day of sailing, 2 / 5 * 400 = 160 pounds of food supplies had been used. The total number of supplies remaining in the ship is 400 - 160 = 240 pounds. After another 2 days of sailing, 3 / 5 * 240 = 144 pounds of food had been used. The total number of supplies remaining in the ship is now 240 - 144 = 96 pounds. The answer is 96.
[Question]The big bottles of mango juice hold 30 ounces and cost 2700 pesetas each. The small bottles hold 6 ounces and cost 600 pesetas each. How many pesetas would be saved by buying a big bottle instead of smaller bottles for the same volume of juice?
[Answer]The equivalent is 30 / 6 = 5 small bottles. Five small bottles at 600 pesetas each is 5 * 600 = 3000 pesetas. The savings is 3000 - 2700 = 300. The answer is 300.
Q: Jake's dad can drive the distance from their house to the water park in 30 minutes. He spends half that journey driving 28 miles per hour and the other half driving 60 miles per hour on the highway. If Jake can bike 11 miles per hour, how many hours will it take him to bike to the water park?
A: First find how long half Jake's dad's trip is: 30 minutes / 2 = 15 minutes. Then convert the minutes to hours: 15 minutes * 1 hour / 60 minutes = .25 hours. Now find how far Jake's dad travels at 28 miles per hour: .25 hours * 28 miles per hour = 7 miles. Then find how far Jake's dad travels at 60 miles per hour: .25 hours * 60 miles per hour = 15 miles. Now add those distances to find the total distance to the water park: 7 miles + 15 miles = 22 miles. Now divide the total distance by Jake's speed to find how long it takes him: 22 miles / 11 miles / hour = 2 hours. The answer is 2.
Question: 3000 bees hatch from the queen's eggs every day. If a queen loses 900 bees every day, how many total bees are in the hive (including the queen) at the end of 7 days if at the beginning the queen had 12500 bees?
Answer: 3000 new bees are born every day. In 7 days there will be 3000 * 7 = 21000 new bees. If each day the queen loses 900 bees, in 7 days there will be 900 * 7 = 6300 fewer bees. If at the beginning the queen had 12500 bees, then at the end of 7 days she will have 12500 + 21000 - 6300 = 27200 bees. The total number of bees in the hive including the queen is 27200 + 1 = 27201. The answer is 27201.
