Question: There are 66 goats at a farm and twice as many chickens. If the number of ducks is half of the total of the goats and chickens, and the number of pigs is a third of the number of ducks, how many more goats are there than pigs?
Answer: There are 66 x 2 = 132 chickens. There are 66 + 132 = 198 goats and chickens. There are are 198 / 2 = 99 ducks. There are 99 / 3 = 33 pigs. There are 66 - 33 = 33 more goats than pigs. The answer is 33.
[Question]Twice Betty's age is the cost of a pack of nuts. Doug, Betty's friend, is 40 years old. If the sum of their ages is 90, and Betty wants to buy 20 packs of the nuts, calculate the amount of money she'll pay for the packs of nuts.
[Answer]If Doug, Betty's friend, is 40 years old, and the sum of their ages is 90, Betty is 90 - 40 = 50 years old. Since twice Betty's age is the cost of a pack of nuts, a pack of nuts is sold at 2 * $50 = $100. If Betty wants to buy 20 packs of the nuts, she'll have to pay 20 * $100 = $2000. The answer is 2000.
Q: Pete has a bag with 10 marbles. 40% are blue and the rest are red. His friend will trade him two blue marbles for every red one. If Pete keeps 1 red marble, how many total marbles does he have after trading with his friend?
A: He starts with 4 blue marbles because 10 x .4 = 4. 60% of the marbles are red because 100 - 40 = 60. He has 6 red marbles because 10 x .6 = 6. He trades 5 red marbles because 6 - 1 = 5. He gets 10 blue marbles because 5 x 2 = 10. He has 15 marbles now because 4 + 1 + 10 = 15. The answer is 15.
Question: Every Sunday, Sean picks up 1 almond croissant and 1 salami and cheese croissant that are $4.50 each. He also grabs a plain croissant for $3.00 and a loaf of focaccia for $4.00. On his way home he stops and picks up 2 lattes for $2.50 each. How much did he spend?
Answer:
The almond croissant and the salami and cheese croissant are $4.50 each so that's 2 * 4.50 = $9.00. He buys 2 lattes that are $2.50 each so that's 2 * 2.50 = $5.00. The flavored croissants are $9.00, the lattes are $5.00 and he also grabbed a plain croissant for $3.00 and focaccia for $4.00 for a total of 9 + 5 + 3 + 4 = $21.00. The answer is 21.
