Question: Violet has 3 more than twice as many nails as Tickletoe. If Violet has 27 nails, how many nails do they have together?
Answer: Violet has 27 - 3 = 24 nails, twice the number of nails that Tickletoe has. Therefore, Tickletoe has 1 / 2 * 24 = 12 nails. Together, Tickletoe and Violet have 12 + 27 = 39 nails. The answer is 39.
[Question]In the jar, there are 7 blue marbles, 11 red marbles, and some yellow marbles. If the chance of randomly picking a yellow marble is 1/4, how many yellow marbles are there?
[Answer]Let y be the number of yellow marbles. There are 11 + 7 + y = 18 + y total marbles. y / (18 + y) = 1 / 4. 4y = 18 + y. 3y = 18. y = 6. There are 6 yellow marbles. The answer is 6.
Q: A highway is being extended from its current length of 200 miles up to 650 miles. 50 miles are built on the first day, and three times this amount are built on the second day. How many miles still need to be added to the highway to finish extending it?
A: The length of the highway that needs to be constructed is 650 – 200 = 450 miles. After the first day, there are still 450 – 50 = 400 miles that need to be constructed. On the second day, 50 miles * 3 = 150 miles are added to the highway. This means that 400 – 150 = 250 miles still need to be added to the highway. The answer is 250.
Question: Bill is making omelets for his family's breakfast. It takes him 3 minutes to chop a pepper, 4 minutes to chop an onion, and 1 minute to grate enough cheese for one omelet. It takes him 5 minutes to assemble and cook the omelet. If he needs to chop up four peppers, two onions, and also grates cheese for cooking each of five omelets, how long will he spend preparing for and cooking the five omelets?
Answer: First find the total time Bill spends chopping peppers: 4 peppers * 3 minutes / pepper = 12 minutes. Then find the total time Bill spends chopping onions: 2 onions * 4 minutes / onion = 8 minutes. Then find the combined time to grate cheese for and cook each omelet: 5 + 1 minute / omelet = 6 minutes. Then multiply the time per omelet by the number of omelets: 5 omelets * 6 minutes / omelet = 30 minutes. Then add the cook time to the chopping time to find the total time Bill spends: 30 minutes + 12 minutes + 8 minutes = 50 minutes. The answer is 50.
[Question]Keanu was surfing towards the shore at a speed of 20 miles per hour. A shark was swimming alongside him, riding the same wave, when it doubled its speed and moved away from Keanu. There was a pilot fish swimming alongside Keanu and the shark, and when the shark increased its speed, the pilot fish also increased its speed and moved away from Keanu, but only increasing its speed by half as much as the shark had increased its speed by. What speed, in miles per hour, was the pilot fish swimming when it moved away from Keanu?
[Answer]The shark went from 20 miles per hour to a speed of 2 * 20 = 40 miles per hour. The shark increased its speed by 40 - 20 = 20 miles per hour. Half of the shark's increase in speed is 20 / 2 = 10 miles per hour. Thus the pilot fish had increased its speed to 20 + 10 = 30 miles per hour. The answer is 30.
[Question]John skateboarded for 10 miles and then walked another 4 miles to the park. He then skated all the way back home. How many miles has John skateboarded in total?
[Answer]

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

John traveled 10 + 4 = 14 miles to the park. His round trip would take 14 x 2 = 28 miles. If you subtract the 4 miles he walked then John traveled 28 - 4 = 24 miles. The answer is 24.
