Q: Billy has four horses. Each one eats 4 pounds of oats, twice a day. How many pounds of oats does he need to feed his horses for 3 days?
A: At each feeding Billy serves 4 horses x 4 pounds of oats / horse = 16 pounds / feeding. Each day Billy uses 16 pounds of oats / feeding x 2 feedings / day = 32 pounds of oats / day. Triple that amount to find the amount of oats needed to feed the four horses for three days: 32 pounds of oats / day x 3 days = 96 pounds. The answer is 96.
Question: A factory produces 90 refrigerators per hour. It also produces 70 more coolers than refrigerators per hour. How many products did the factory produce for 5 days if it works 9 hours a day?
Answer: The factory produces 90 + 70 = 160 coolers per hour. The factory works 5 * 9 = 45 hours in 5 days. The factory produces ( 90 + 160) * 45 = 11250 products for 5 days. The answer is 11250.
[Question]Frank is making hamburgers and he wants to sell them to make $50. Frank is selling each hamburger for $5 and 2 people purchased 4 and another 2 customers purchased 2 hamburgers. How many more hamburgers does Frank need to sell to make $50?
[Answer]Frank sold 4 hamburgers and then sold 2 more, so all together Frank already sold 4 + 2 = 6 hamburgers. If each hamburger is $5 and he sold 6 hamburgers already, Frank has made 5 * 6 = 30 dollars. Frank wants to make $50 and has already made $30, so Frank still needs 50 - 30 = 20 dollars. Since he needs $20 and each hamburger is $5, Frank needs to sell 20 / 5 = 4 more hamburgers. The answer is 4.
Q: Marj has two $20 bills, three $5 bills, and $4.50 in loose coins in her wallet. If she buys a cake that costs $17.50, how much money will be left in her wallet?
A: Two $20 bills amount to $20 x 2 = $40. Three $5 bills amount to $5 x 3 = $15. So, Marj has $40 + $15 + $4.50 = $59.50 in her wallet. If she buys a cake, she will be left with $59.50 - $17.50 = $42. The answer is 42.
Question: It takes a duck 40 days to fly to the south during winter, twice as much time to fly to the north during summer, and 60 days to travel to the East during spring. How many days is the duck flying during these seasons?
Answer: If the duck takes 40 days to fly to the south during winter and twice as much time to fly to the north during summer, it takes 40 * 2 = 80 days to travel to the north. The total time it takes to travel to the south and the north during both seasons is 80 + 40 = 120 days. The duck also takes 60 days to travel to the East during spring, making the total time it travels during all the seasons to be 120 + 60 = 180. The answer is 180.
