Q: Bruce buys 5 packs of crayons at $5 each, 10 books at $5 each, and 3 calculators at $5 each. If he has $200, how many bags can he buy with the change if one costs $10 each?
A: He pays 5 * 5 = $25 for buying crayons. He pays 10 * 5 = $50 for buying books. He pays 3 * 5 = $15 for buying calculators. The change he has for buying bags is 200 - 25 - 50 - 15 = $110. The number of bags he can buy is 110 / 10 = 11 bags. The answer is 11.
Question: There are 480 grains of rice in one cup. If half a cup is 8 tablespoons and one tablespoon is 3 teaspoons, how many grains of rice are in a teaspoon?
Answer: First find the number of tablespoons in a full cup: 8 tablespoons / half - cup * 2 half - cups / cup = 16 tablespoons. Then find the total number of teaspoons in a cup: 16 tablespoons / cup * 3 teaspoons / tablespoon = 48 teaspoons. Then find the number of grains of rice per teaspoon: 480 grains / 48 teaspoons = 10 grains / teaspoon. The answer is 10.
[Question]Tony puts $1,000 in a savings account for 1 year. It earns 20% interest. He then takes out half the money to buy a new TV. The next year, the remaining money earns 15% interest. How much is now in the account?
[Answer]After one year he earns $200 in interest because 1,000 x .2 = 200. After one year it has $1,200 in the account because 1,000 + 200 = 1,200. He takes out $600 because 1,200 / 2 = 600. After this it has $600 in it because 1,200 - 600 = 600. She earns $90 in interest because 600 x .15 = 90. The account now has $690 because 600 + 90 = 690. The answer is 690.
Q: Ephraim has two machines that make necklaces for his store. On Sunday the first machine made 45 necklaces. The second machine made 2.4 times as many necklaces as the first machine. How many necklaces were made in total on Sunday?
A: The second machine made 2.4 times as many necklaces as the first machine, so the second machine made 2.4 * 45 = 108 necklaces on Sunday. In total, 45 + 108 = 153 necklaces were made on Sunday. The answer is 153.
Question: A teacher asked Adelaide, Ephraim, and Kolton to buy ducks and monitor their growth patterns and features for their science class. Adelaide bought twice the number of ducks that Ephraim bought, while Ephraim bought 45 fewer ducks than Kolton. If Adelaide bought 30 ducks, what's the average number of ducks the three bought?
Answer: If Adelaide bought 30 ducks, Ephraim bought 30 ducks / 2 = 15 ducks. Since Ephraim bought 45 fewer ducks than Kolton, Kolton bought 45 ducks + 15 ducks = 60 ducks. The total number of ducks the three bought is 60 ducks + 15 ducks + 30 ducks = 105 ducks. The average number of ducks each bought is 105 ducks / 3 people = 35 ducks / person. The answer is 35.
Q: Wayne wants to serve shrimp cocktail as an appetizer. He plans on 5 shrimp per guest and will have 40 guests. If the shrimp costs $17.00 per pound and each pound has 20 shrimp, how much will he spend on the appetizer?
A:
He wants to serve 5 shrimp per guest and will have 40 guests so he needs 5 * 40 = 200 shrimp. Each pound of shrimp has 20 shrimp and he needs 200 shrimp so he needs 200 / 20 = 10 pounds of shrimp. The shrimp is $17.00 per pound and he needs 10 pounds so he will spend 17 * 10 = $170.00 on shrimp. The answer is 170.
