Question: John decides to get gym memberships so he can get in shape. The gym close to his house is close but doesn't have everything he wants so he gets two different gym memberships. The cheap one costs $10 a month and has a sign-up fee of $50. The second gym is 3 times more expensive and it has a sign-up fee of 4 months membership. How much total did he pay in the first year for gym membership?
Answer: The cheap gym cost 10 * 12 = $120 for monthly fees. So the total cost was 120 + 50 = $170. The more expensive gym cost 3 * 10 = $30 per month. That means the sign - up fee was 30 * 4 = $120. The monthly fees for the expensive gym comes out to 30 * 12 = $360 per year. So the total cost for the expensive gym was 360 + 120 = $480. So his total cost was 480 + 170 = $650. The answer is 650.
[Question]Clara brings a package of 100 stickers to school. She gives 10 stickers to a boy she likes. She gives half of the stickers which she has left to her best friends. How many stickers does Clara have left?
[Answer]She gives the boy she likes 10 stickers. After giving the boy his stickers, she has 100 – 10 = 90 stickers left. She gives her best friends 90 / 2 = 45 stickers. This leaves Clara with 90 – 45 stickers = 45 stickers. The answer is 45.
Q: There are 18 green leaves on each of the 3 tea leaf plants. One-third of them turn yellow and fall off on each of the tea leaf plants. How many green leaves are left on the tea leaf plants?
A: In total, the 3 tea leaf plants have 18 x 3 = 54 green leaves. One - third of the yellow leaves falling off of all plants is 54 / 3 = 18. The number of remaining green leaves on the plants is 54 - 18 = 36. The answer is 36.
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.
Q: Holly wants to plant a wall of privacy trees along her fence line. Her fence is 25 yards long. At maturity, the trees she wants to plant will measure 1.5 feet wide. Right now, these trees are on sale for $8.00 apiece. How much will it cost her to plant a row of the trees to run the length of her fence?
A:
3 feet are in 1 yard and her fence is 25 yards long so her fence is 3 * 25 = 75 feet long. At maturity these trees will measure 1.5 feet and she needs them to run along her 75 - foot fence so she needs 75 / 1.5 = 50 trees. The trees cost $8.00 apiece and she needs 50 so 8 * 50 = $400.00 worth of trees. The answer is 400.
