Q: Marla is planning the lunch menu for an elementary school. There are 5 third grade classes with 30 students each, 4 fourth grade classes with 28 students each, and 4 fifth grade classes with 27 students each. Each student gets a hamburger, which costs $2.10, some carrots, which cost $0.50, and a cookie, which cost $0.20. How much does one lunch for all the students cost?
A: First find the total number of students in third grade 5 classes * 30 students / class = 150 students. Then find the total number of students in fourth grade 4 classes * 28 students / class = 112 students. Then find the total number of student in fifth grade 4 classes * 27 students / class = 108 students. Now add the number of students in each grade to find the total number of students 150 students + 112 students + 108 students = 370 students. Now find the total cost of one lunch $2.10 + $0.50 + $0.20 = $2.80. Now multiply that cost by the number of students to find the total cost for the school $2.80 / student * 370 students = $1036. The answer is 1036.

[Question]Linda's bag has 2 dimes, 6 quarters, and 5 nickels. Her mother gives her 2 more dimes, 10 quarters, and twice as many nickels as she has. How many coins does she have altogether?
[Answer]When Linda's mother gave her 2 more dimes, the total number of dimes increased to 2 + 2 = 4 dimes. She also increased the total number of quarters to 6 + 10 = 16 after her mother gave her 10 more. The total number of dimes and quarters she has is 16 + 4 = 20. Linda's mother also gave her twice as many nickels as she has, a total of 2 * 5 = 10 nickels. The total number of nickels she has increased to 10 + 5 = 15. Altogether, Linda has 20 + 15 = 35 coins. The answer is 35.

Question: A waterpark opens up and charges $30 for admission. Kids' tickets are half price. If a group of people brings a soda, they can get 20% off the total price of admission. Janet gets tickets for 10 people and 4 of them are children. She buys a soda for $5 to take advantage of the discount for her group. How much did she pay for everything?
Answer:
She bought 10 - 4 = 6 adult tickets. So 6 * 30 = $180 was the cost for adult tickets. Children tickets cost 30 / 2 = $15 each. So the children tickets cost 15 * 4 = $60. So the total cost of tickets is 60 + 180 = $240. They get a 240 * .2 = $48 discount. So the tickets cost 240 - 48 = $192. So in total she paid 192 + 5 = $197. The answer is 197.
