[Question]Tina buys 3 12-packs of soda for a party. Including Tina, 6 people are at the party. Half of the people at the party have 3 sodas each, 2 of the people have 4 and 1 person has 5. How many sodas are left over when the party is over?
[Answer]Tina buys 3 12 - packs of soda, for 3 * 12 = 36 sodas. 6 people attend the party, so half of them is 6 / 2 = 3 people. Each of those people drinks 3 sodas, so they drink 3 * 3 = 9 sodas. Two people drink 4 sodas, which means they drink 2 * 4 = 8 sodas. With one person drinking 5, that brings the total drank to 5 + 9 + 8 = 22 sodas. As Tina started off with 36 sodas, that means there are 36 - 22 = 14 sodas left. The answer is 14.
Q: Lucy plans to purchase potato chips for a party. Ten people will be at the party, including Lucy. The potato chips cost 25 cents per pound. How much will Lucy pay (in dollars) for the potato chips if she wants each person to get 1.2 pounds?
A: Lucy needs to purchase 10 x 1.2 = 12 pounds of potato chips. So, Lucy will pay 12 x 25 = 300 cents for it. Since there are 100 cents in $1, thus, Lucy will pay 300 / 100 = 3 dollars. The answer is 3.
Question: Onum Lake has 25 more trout than Boast Pool.  There are 75 fish in Boast Pool. Riddle Pond has half as many fish as Onum Lake. What is the average number of fish in all three bodies of water?
Answer: Onum lake has 25 trout + 75 = 100 fish. Riddle Pond has 1 / 2 * 100 fish in Onum lake = 50 fish. Combined the three bodies of water have 100 fish + 50 fish + 75 fish = 225 fish. The average number of fish in the bodies of water is 225 fish / 3 = 75 fish. The answer is 75.
[Question]A curry house sells curries that have varying levels of spice. Recently, a lot of the customers have been ordering very mild curries and the chefs have been having to throw away some wasted ingredients. To reduce cost and food wastage, the curry house starts monitoring how many ingredients are actually being used and changes their spending accordingly. The curry house needs 3 peppers for very spicy curries, 2 peppers for spicy curries, and only 1 pepper for mild curries. After adjusting their purchasing, the curry house now buys the exact amount of peppers they need. Previously, the curry house was buying enough peppers for 30 very spicy curries, 30 spicy curries, and 10 mild curries. They now buy enough peppers for 15 spicy curries and 90 mild curries. They no longer sell very spicy curries. How many fewer peppers does the curry house now buy?
[Answer]The curry house previously bought 3 peppers per very spicy curry * 30 very spicy curries = 90 peppers for very spicy curries. They also bought 2 peppers per spicy curry * 30 spicy curries = 60 peppers for spicy curries. They also bought 1 pepper per mild curry * 10 mild curries = 10 peppers for mild curries. So they were previously buying 90 + 60 + 10 = 160 peppers. They now buy 2 peppers per spicy curry * 15 spicy curries = 30 peppers for spicy curries. They also now buy 1 pepper per mild curry * 90 mild curries = 90 peppers for mild curries. So they now buy 30 + 90 = 120 peppers. This is a difference of 160 peppers bought originally - 120 peppers bought now = 40 peppers. The answer is 40.
Q: Vince owns a hair salon and he earns $18 per head. His monthly expenses are $280 for rent and electricity and 20% of his earnings are allocated for recreation and relaxation. He will save the rest. How much does he save if he serves 80 customers a month?
A: This month, Vince earns 80 x $18 = $1440. The amount he allocates for recreation and relaxation is 20 / 100 x $1440 = $288. Thus, his monthly expenses is $280 + $288 = $568. Therefore, he saves $1440 - $568 = $872. The answer is 872.
Question: Mary bought six apples from the store. From the apples she bought, for each that Mary ate, she planted two trees from the remaining ones. How many apples did Mary eat?
