Question: A bear is preparing to hibernate for the winter and needs to gain 1000 pounds. At the end of summer, the bear feasts on berries and small woodland animals. During autumn, it devours acorns and salmon. It gained a fifth of the weight it needed from berries during summer, and during autumn, it gained twice that amount from acorns. Salmon made up half of the remaining weight it had needed to gain. How many pounds did it gain eating small animals?
Answer: The bear gained 1 / 5 * 1000 = 200 pounds from berries. It gained 2 * 200 = 400 pounds from acorns. It still needed 1000 - 200 - 400 = 400 pounds. Thus, it gained 400 / 2 = 200 pounds from salmon. Therefore, the bear gained 400 - 200 = 200 pounds from small animals. The answer is 200.
[Question]Andy is mixing blue, green and white paint in a 1 : 2 : 5 ratio. If he uses 6 gallons of green paint, how many gallons of paint does he use total?
[Answer]First find the number of gallons of blue paint by multiplying the gallons of green paint by the ratio between the blue and green paint: 1 blue gallon / 2 green gallons * 6 gallons = 3 gallons. Then find the number of gallons of white paint by multiplying the gallons of green paint by the ratio between the white and green paint: 5 white gallons / 2 green gallons * 6 gallons = 15 gallons. Then add the number of gallons of each color to find the total number of gallons of paint: 6 gallons + 3 gallons + 15 gallons = 24 gallons. The answer is 24.
Q: James takes a spinning class 3 times a week. He works out for 1.5 hours each class and burns 7 calories per minute. How many calories does he burn per week?
A: He works out for 1.5 * 60 = 90 minutes per class. So he burns 90 * 7 = 630 calories per class. That means he burns 630 * 3 = 1890 calories per week. The answer is 1890.
Question: Gabby is saving money to buy a new makeup set. The makeup set costs $65 and she already has $35. Gabby’s mom gives her an additional $20. How much money does Gabby need to buy the set?

[Question]A printing press is printing brochures. The press prints 20 single-page spreads, and twice as many double-page spreads. For each 4 pages printed for the spreads, the press prints a block of 4 ads, each of which take up a quarter of a page. The brochures can be arranged in any order as long as they are made up of 5 pages each. How many brochures is the printing press creating?
[Answer]There are a total of 20 single - page spreads * 2 = 40 double - page spreads. As these are made up of 2 pages each, there are 40 double - page spreads * 2 pages = 80 pages in the double - page spreads. In total, there are 20 single - pages + 80 double - pages = 100 pages in the spreads. A block of ads is printed every 4 pages, so there will be 100 pages / 4 pages / block = 25 blocks of ads. This is a total of 25 blocks * 4 ads = 100 ads. As each ad takes up a quarter of a page, this must create an additional 100 ads * 0.25 = 25 pages. Therefore, the press has printed 100 pages from the spreads + 25 pages of ads = 125 pages. Since brochures are made up of 5 pages each, this creates a total of 125 pages / 5 = 25 brochures. The answer is 25.
[Question]A soccer ball takes twenty minutes to inflate. Alexia and Ermias are inflating balls, with Alexia inflating 20 balls and Ermias inflating 5 more balls than Alexia. Calculate the total time in minutes they took to inflate all the soccer balls.
[Answer]
To inflate a soccer ball, it takes 20 minutes, and if Alexia inflated 20 soccer balls, she took 20 * 20 = 400 minutes. Ermias has 5 more soccer balls than Alexia, meaning she has a total of 20 + 5 = 25 soccer balls. If each soccer ball takes 20 minutes to inflate, Ermias took 25 * 20 = 500 minutes to inflate all the soccer balls she had. Alexia and Ermias took 400 + 500 = 900 minutes to inflate all the soccer balls. The answer is 900.
