[Question]Daragh had 20 stuffed bears. She took out her favorite 8 bears and then equally divided the other bears among her 3 sisters. Daragh's youngest sister, Eden, already had 10 stuffed bears. How many stuffed bears does Eden have now?
[Answer]Take the number of bears Daragh has left after taking her favorite 8 bears out: 20 bears - 8 bears = 12 bears. Divide these amongst Daragh's 3 sisters: 12 bears / 3 sisters = 4 bears per sister. Add the 4 bears to Eden's current bears: 10 bears + 4 bears = 14 bears. The answer is 14.
Q: John has 25 horses. He feeds each horse twice a day and feeds them 20 pounds of food at each feeding. He buys half ton bags of food. How many of those will he have to buy in 60 days?
A: He feeds each horse 2 * 20 = 40 pounds of food a day. So he uses 40 * 25 = 1000 pounds of food a day. That means in 60 days he uses 60 * 1000 = 60000 pounds of food. Each bag of food is 2000 * .5 = 1000 pounds. So he needs to buy 60000 / 1000 = 60 bags of food. The answer is 60.
Question: Jack leaves his bathtub's faucet dripping at a rate of 40 ml/minute. Water evaporates from the bathtub at a rate of 200 ml/hour. If he leaves the water running for 9 hours, then dumps out 12 liters, how many milliliters of water are left in the bathtub?
Answer: First find how much water fills the bathtub per hour: 40 ml / minute * 60 minutes / hour = 2400 ml / hour. Then subtract the water that evaporates to find the total amount of water added per hour: 2400 ml / hour - 200 ml / hour = 2200 ml / hour. Then multiply that amount by the number of hours to find the total amount of water in the tub: 2200 ml / hour * 9 hours = 19800 ml. Then find the number of milliliters in 12 liters: 12 liters * 1000 ml / liter = 12000 ml. Then subtract the water Jack removes from the total amount of water to find the remaining amount of water: 19800 ml - 12000 ml = 7800 ml. The answer is 7800.
[Question]A community is building a metal fence. Each fence panel is made of 3 metal sheets, and 2 metal beams. The fence is made of 10 fence panels. If each sheet is made of 10 metal rods and each metal beam is made of 4 metal rods, how many metal rods does the community need for the fence?
[Answer]In each panel, the metal sheets use 3 metal sheets * 10 metal rods = 30 metal rods. In each panel, the metal beams use 2 metal beams * 4 metal rods = 8 metal rods. So each panel uses 30 + 8 = 38 metal rods. The entire fence therefore needs 38 metal rods * 10 fence panels = 380 metal rods. The answer is 380.
Q: The fisherman gets 8 Red snappers and 14 Tunas every day. If a Red snapper costs $3 and a Tuna costs $2, how much does he earn every day?
A: The fisherman earns $3 x 8 = $24 per day on Red snappers. He earns $2 x 14 = $28 per day on Tunas. Therefore, the total amount he earns is $24 + $28 = $52. The answer is 52.
Question: A busy port has 4 cruise ships and twice as many cargo ships. The number of sailboats is 6 more than the cargo ships and seven times more than fishing boats. How many vessels are there on the water?
Answer:
There are 4 x 2 = 8 cargo ships. There are 8 + 6 = 14 sailboats. There are 14 / 7 = 2 fishing boats. There are 4 + 8 + 14 + 2 = 28 vessels on the water. The answer is 28.
