[Question]Layla is feeding her pet fish. She has two Goldfish which each get one teaspoon of fish food. Her 3 Swordtails each get 2 teaspoons of food. Her 8 Guppies each eat half a teaspoon of food. How much food does she have to give to her fish in total?
[Answer]The two Goldfish eat a total of 2 * 1 = 2 teaspoons of food. The 3 Swordtails eat a total of 3 * 2 = 6 teaspoons of food. The 8 Guppies eat a total of 8 * 1 / 2 = 4 teaspoons of food. In total, all of her fish eat 2 + 6 + 4 = 12 teaspoons of fish food. The answer is 12.
Q: Jeffrey owns a poultry farm with 12 hens. For every 3 hens, there is 1 rooster. Each hen has 5 chicks. How many chickens are there in all?
A: Jeffrey’s poultry farm has 12 / 3 = 4 roosters. There are 12 * 5 = 60 chicks. Thus, there are 12 + 4 + 60 = 76 chickens on the poultry farm. The answer is 76.
Question: In a restaurant, one cup of coffee is $6 and a piece of cheesecake $10. When buying them together, the client gets a 25% discount. What is the final price of such a set?
Answer: Both the cheesecake and coffee cost 10 + 6 = $16. The discount for these items is 25 / 100 * 16 = $4. So the final price for the cheesecake and coffee is 16 - 4 = $12. The answer is 12.
[Question]Andy needs to drive from Salt Lake City to Los Angeles. The drive from Salt Lake City to Las Vegas is 420 miles. The drive from Las Vegas to Los Angeles is 273 miles. He wants to make the drive in 11 hours. What's the average minimum speed that Andy needs to drive to reach Los Angeles in 11 hours?
[Answer]The total distance of the trip is 420 + 273 = 693 miles. To make the trip Andy must drive 693 miles / 11 hours = 63 miles per hour. The answer is 63.
Q: Tom broke his leg and needed to go to the doctor. The visit cost $300 and the cast cost $200. If insurance covered 60% how much was Tom's out-of-pocket cost?
A: The cost was 300 + 200 = $500. So insurance paid for 500 * .6 = $300. That means he had to pay 500 - 300 = $200 out of pocket. The answer is 200.
Question: Jerry takes 2 antacids that weigh 2 grams each and are 5% zinc by weight. Then he takes three more smaller antacids that weigh 1 gram each and have 15% zinc. How many milligrams of zinc does he eat?
Answer:
First find the total weight of the big antacids: 2 grams / antacid * 2 antacids = 4 grams. Then convert that weight to milligrams: 4 grams * 1000 mg / gram = 4000 mg. Then multiply that number by 5% to find how much zinc is in the big antacids: 4000 mg * 5% = 200 mg. Then find the total weight of the smaller antacids in milligrams: 3 antacids * 1 gram / antacid * 1000 mg / gram = 3000 mg. Then multiply that number by the percent of zinc to find the amount of zinc in the small antacids: 3000 mg * 15% = 450 mg. Then add the zinc Jerry gets from each set of pills to find the total amount of zinc he eats: 450 mg + 200 mg = 650 mg. The answer is 650.
