Question: Alicia has to buy some books for the new school year. She buys 2 math books, 3 art books, and 6 science books, for a total of $30. If both the math and science books cost $3 each, what was the cost of each art book?
Answer: The total cost of maths books is 2 * 3 = 6 dollars. The total cost of science books is 6 * 3 = 18 dollars. The total cost for maths and science books is 6 + 18 = 24 dollars. The cost for art books is 30 - 24 = 6 dollars. Since he bought 3 art books, the cost for each art book will be 6 / 3 = 2 dollars. The answer is 2.
[Question]Jacob's water tank can hold up to 50 liters of water. Jacob collects water from the river and rain to fill his water tank. He can collect 800 milliliters of water from the rain and 1700 milliliters of water from the river every day. How many days does Jacob need to fill up his water tank?
[Answer]Jacob collects 800 + 1700 = 2500 milliliters of water from the river and rain every day. Since 1 liter is equal to 1000 milliliters, then 50 liters is equal to 50x1000 = 50,000 milliliters of water. Therefore Jacob needs 50,000 / 2500 = 20 days to fill his water tank. The answer is 20.
Q: Aaron and his brother Carson each saved up $40 to go to dinner. The bill is 3/4 of their total money. After, they go out for ice cream. Each scoop costs $1.5 and they get the same amount as each other. If they leave with $1 in change each, how many scoops did they each buy?
A: They had $80 saved up because 2 x 40 = 80. They spent $60 because 80 x (3 / 4) = 60. They had $20 left for ice cream because 80 - 60 = 20. They had $2 left after leaving the ice cream shop because 2 x 1 = 2. They spent $18 on ice cream because 20 - 2 = 18. The bought 12 scoops of ice cream because 18 / 1.5 = 12. The each bought 6 scoops because 12 / 2 = 6. The answer is 6.

[Question]Half of Taylor's house guests like weak coffee and the other half like strong coffee in the morning. Taylor uses 1 tablespoon of coffee per cup of water to make it weak and he doubles that amount to make it strong. If he makes 12 cups of both weak and strong coffee, how many tablespoons of coffee will he need?
[Answer]
He uses 1 tablespoon for weak coffee and doubles that for strong so the strong uses 1 * 2 = 2 tablespoons. For the weak coffee he uses 1 tablespoon per 1 cup of water and he needs to make 12 cups so he'll use 1 * 12 = 12 tablespoons. For the strong coffee he uses 2 tablespoons per 1 cup of water and he needs to make 12 cups so he'll use 2 * 12 = 24 tablespoons. All total he will use 12 tablespoons for the weak coffee and 24 tablespoons for the strong coffee for a total of 12 + 24 = 36 tablespoons. The answer is 36.
