Q: Casey is going to stay at a motel while she works her summer job as a ski instructor. The hotel charges $280/week or $1000/month. If Casey will be staying 3 months, each with exactly 4 weeks, how much money does she save by paying monthly?
A: First find the number of weeks Casey stays: 3 months * 4 weeks / month = 12 weeks. Then multiply that number by the weekly rate to find how much she would pay weekly: 12 weeks * $280 / week = $3360. Then multiply the number of months she stays by the monthly rate to find how much she pays monthly: $1000 / month * 3 months = $3000. Then subtract that number from the total amount she pays if she pays weekly to find her savings: $3360 - $3000 = $360. The answer is 360.
Question: American carmakers produce 5 650 000 cars each year. Then they distribute it to 5 car suppliers. The first supplier receives 1 000 000 cars each. The second supplier receives 500 000 cars more while the third car supplier receives the same number as the first and second suppliers combined. The fourth and the fifth supplier receive an equal number of cars. How many cars do the fourth and fourth suppliers each receive?
Answer: The second supplier receives 1 000 000 + 500 000 = 1 500 000 cars. The third supplier receives 1 000 000 + 1 500 000 = 2 500 000 cars. So the first to third suppliers receive a total of 1 000 000 + 1 500 000 + 2 500 000 = 5 000 000 cars. Thus, 5 650 000 - 5 000 000 = 650 000 cars are left to be divided by the two other suppliers. Therefore, the fourth and fifth suppliers receive 650 000 / 2 = 325 000 cars each. The answer is 325000.
[Question]Diane bakes four trays with 25 gingerbreads in each tray and three trays with 20 gingerbreads in each tray. How many gingerbreads does Diane bake?
[Answer]Four trays have 4 x 25 = 100 gingerbreads. And three trays have 3 x 20 = 60 gingerbreads. Therefore, Diane bakes 100 + 60 = 160 gingerbreads. The answer is 160.
Q: Jill makes scented candles as a hobby. Her favorite scents are lavender, coconut, and almond, and she uses the same amount of each scent for every candle. This time, she made twice as many lavender candles as coconut candles, along with a batch of almond candles. She ran out of almond scent after making ten candles. If she had one and a half times as much coconut scent as almond scent and used all her coconut scent up too, how many lavender candles did she make?
A: Jill made one and a half times as many coconut candles as almond candles, so she made 10 * 1 1 / 2 = 15 coconut candles. She made twice as many lavender candles as coconut candles, so she made 2 * 15 = 30 lavender candles. The answer is 30.
Question: John adopts a dog from a shelter. The dog ends up having health problems and this requires 3 vet appointments, which cost $400 each. After the first appointment, John paid $100 for pet insurance that covers 80% of the subsequent visits. How much did he pay in total?
Answer:
He got a discount of 400 * .8 = $320. He got that discount for 3 - 1 = 2 visits. So each of those visits cost 400 - 320 = $80. So he paid 2 * 80 = $160 for those visits. That means he paid a total of 400 + 160 + 100 = $660. The answer is 660.
