Q: Krista started raising chickens. She has 10 hens who lay eggs. She sells the eggs for $3 a dozen. In four weeks, she sold $120 worth of eggs. If she sold all the eggs her hens laid, how many eggs does each hen lay a week?
A: At $3 a dozen, Krista sold $120 / $3 = 40 dozen eggs. If 10 hens laid 40 dozen eggs in 4 weeks, that means 40 dozen eggs / 10 hens = 4 dozen eggs were laid by each hen in four weeks. To find out how many eggs each hen laid in a week, 4 dozen eggs / 4 weeks = 1 dozen eggs each week. Since a dozen has 12 eggs, each hen lays 12 * 1 = 12 eggs each week. The answer is 12.
Question: Hanna has twice as many erasers as Rachel. Rachel has three less than one-half as many erasers as Tanya has red erasers. If Tanya has 20 erasers, and half of them are red, how many erasers does Hanna have?
Answer: Half of Tanya's 20 erasers are red, so she has 20 / 2 = 10 red erasers. One - half as many erasers as Tanya has red erasers is 10 / 2 = 5 red erasers. Rachel's three less than one - half as many erasers as Tanya's red erasers, which is 5 - 3 = 2 erasers. Hanna has twice as many erasers as Rachel, for a total of 2 * 2 = 4 erasers. The answer is 4.
[Question]A coffee shop brews 10 coffee cups per hour on a weekday and 120 coffee cups in total over the weekend. If the coffee shop is open 5 hours a day every single day, how many coffee cups are brewed in 1 week?
[Answer]On a weekday, the shop produces 10 coffee cups per hour * 5 hours per weekday = 50 coffee cups. The coffee shop therefore brewed 50 coffee cups per day * 5 weekdays in a week = 250 coffee cups. So in total, the coffee shop brewed a total of 250 weekday coffee cups + 120 weekend coffee cups = 370 coffee cups in 1 week. The answer is 370.
Q: Rob and Mark plan to meet at the national park. It takes 1 hour for Rob to get to the national park and it takes three times as much time for Mark to get to the national park. If Rob leaves his home at 11 a.m., at what time should Mark leave his home so that they both arrive at the same time?
A: It takes 1 hour * 3 = 3 hours for Mark to get to the national park. The extra time it takes Mark to get to the national park is 3 hours - 1 hour = 2 hours. Mark should leave his home at 11 a.m. - 2 hours = 9 a.m. The answer is 9.
Question: A family is going to the amusement park. The adult tickets cost $22 for admission, and the tickets for children cost $7. The family consists of 2 adults and 2 children. What is the total price the family will pay for admission?
Answer: To solve this problem you can set up an equation to represent the total price the family will pay, with a representing the number of adult tickets, c representing the number of children’s tickets, and p representing the total price of admission. Thus 22a + 7c = p. Plug in the number of adults and children that plan to go to the amusement park: 22(2) + 7(2) = $58 is the total cost for admission. The answer is 58.
Q: Wyatt's mother gave him $74 to go to the store. Wyatt bought 5 loaves of bread and 4 cartons of orange juice. Each loaf of bread cost $5 and each carton of orange juice cost $2. How much money does Wyatt have left?
A:
The loaves of bread cost 5 * $5 = $25. The orange juice cost 4 * $2 = $8. Wyatt’s total cost is $25 + $8 = $33. Wyatt is left with the initial $74 - $33 = $41. The answer is 41.
