Q: Francis' family has 2 ukuleles, 4 guitars, and a certain number of violins. Each ukulele has 4 strings. Each guitar has 6 strings. Each violin has 4 strings. If the total number of strings among the ukuleles, guitars, and violins is 40 strings, how many violins does Francis' family have?
A: From the ukuleles, there are 2 * 4 = 8 strings. From the guitars, there are 4 * 6 = 24 strings. From the violins, there are 40 - 8 - 24 = 8 strings. The total number of violins Francis' family has is 8 / 4 = 2 violins. The answer is 2.

[Question]Mark goes into the store to buy some groceries. He buys 6 2$ cans of soup, 2 $5 loaves of bread, 2 3$ boxes of cereal, and 2 $4 gallons of milk. When he gets to the register, he opens his wallet to pay and realizes he only has $10 bills in there. How many $10 bills does he need to use to pay?
[Answer]Mark buys 6 $2 cans of soup, meaning he spends 6 * 2 = 12 dollars on soup. Mark buys 2 $5 loaves of bread, meaning he spends 2 * 5 = 10 dollars on bread. Mark buys 2 $3 boxes of cereal, meaning he spends 2 * 3 = 6 dollars on cereal. Mark buys 2 $4 gallons of milk, meaning he spends 2 * 4 = 8 dollars on milk. All added together, this means Mark spends 12 + 10 + 6 + 8 = 36 dollars. Since Mark only has $10 bills, he spends 36 / 10 = 3.6 tens on it, which rounds up to 4 as you cannot spend .6 of an undividable item. The answer is 4.
Q: James builds a 20 story building. The first 10 stories are each 12 feet tall each. The remaining floors are each 3 feet taller. How tall is the building?
A: The first 10 floors are 10 * 12 = 120 feet. There are a remaining 20 - 10 = 10 stories. They are each 12 + 3 = 15 feet. So those stories are 15 * 10 = 150 feet. So the total height is 120 + 150 = 270 feet. The answer is 270.
Question: Jim decides he wants to practice for a marathon coming up. He starts off by running 5 miles every day for 30 days straight. He then pushes himself to run 10 miles a day for the next 30 days. Finally, as marathon day gets closer Jim runs 20 miles a day for 30 days straight. How many miles does Jim run in total during the 90 days?
Answer: Jim runs 5 miles a day for 30 days for a total of 5 * 30 = 150 miles. The next month Jim runs 10 miles a day for 10 * 30 = 300 miles. The last month Jim runs 20 miles a day for 20 * 30 = 600 a month. All together, Jim runs 150 + 300 + 600 = 1050 miles in three months. The answer is 1050.
Q: On Thursday Walmart sold 210 pounds of ground beef. On Friday they sold twice that amount. On Saturday they only sold 150 pounds. What was the average amount of beef sold per day?
