Question: Anna, Alison, and Jeff collect stamps. Anna had 37 stamps in her collection, Alison had 28 stamps in her collection, and Jeff had 31 stamps in his collection. Alison gave Anna half of her collection in exchange for a novel, and then Anna traded Jeff two bluebird stamps for one mountain stamp. How many stamps did Anna have in the end?
Answer: Alison gave Anna 1 / 2 * 28 = 28 / 2 = 14 stamps. Adding Alison's stamps to Anna's collection means Anna has 14 + 37 = 51 stamps. Then Anna traded Jeff 2 stamps, so she had 51 - 2 = 49 stamps. Anna got 1 stamp back in the trade, so she had 49 + 1 = 50 stamps in the end. The answer is 50.
[Question]A roadwork company is paving a newly constructed 16-mile road. They use a mixture of pitch and gravel to make the asphalt to pave the road. Each truckloads of asphalt uses two bags of gravel and five times as many bags of gravel as it does barrels of pitch to make. It takes three truckloads of asphalt to pave each mile of road. The company paved 4 miles of road on one day, then one mile less than double that on the second day. How many barrels of pitch will the company need to finish the remaining road on the third day?
[Answer]On the second day, the company paved 4 * 2 - 1 = 7 miles. The company has 16 - 7 - 4 = 5 miles of road remaining to pave. They will need 3 * 5 = 15 truckloads of asphalt to pave 5 miles of road. For 15 truckloads, they will need 15 * 2 = 30 bags of gravel. Thus, the company will need 30 / 5 = 6 barrels of pitch to finish the road on the third day. The answer is 6.
Q: Federal guidelines recommend eating at least 2 cups of vegetables per day. From breakfast on Sunday to the end of the day on Thursday, Sarah has eaten 8 cups. How many cups per day does Sarah need to eat of her vegetables in order to meet her daily minimum requirement for the week?
A: There are 7 days in a week and 2 cups are recommended per day, bringing the total to 7 days * 2 cups / day = 14 cups for the week. Out of the 14 total cups needed for the week, Sarah has already eaten 8, for a total of 14 cups - 8 cups = 6 cups left to consume for the week. Sunday through Thursday equals 5 days that have passed. If there are 7 days in the week then Sarah has 7 days - 5 days = 2 days left of the week. If she needs to eat 6 more cups in the next 2 days then she will have to eat 6 cups / 2 days = 3 cups per day over the next two days. The answer is 3.
Question: John buys 1000 balloons. Each balloon holds 10 liters of air. If he buys 500-liter tanks of gas, how many tanks does he need to buy to fill all the balloons?

[Question]In her first term, Governor Sandoval gave twice as many commencement addresses as Governor Hawkins. Governor Sloan gave ten more commencement addresses than Governor Sandoval in the same amount of time. If Governor Sandoval gave 12 commencement addresses, how many commencement addresses did the three of them give altogether?
[Answer]Since Governor Sandoval gave 12 commencement addresses, twice the number that Governor Hawkins gave, Governor Hawkins gave 12 / 2 = 6 commencement addresses. The two of them gave 6 + 12 = 18 commencement addresses in total. Governor Sloan gave ten more commencement addresses than Governor Sandoval, a total of 12 + 10 = 22 commencement addresses. The three of them gave 22 + 18 = 40 commencement addresses. The answer is 40.
