[Question]There are 20 dolphins in the aqua park. One-fourth of the dolphins are fully trained. Two-third of the remaining dolphins are currently in training and the rest will be trained next month. How many dolphins will be trained next month?
[Answer]20 x 1 / 4 = 5 dolphins are fully trained. So, 20 - 5 = 15 dolphins are not yet fully trained. 15 x 2 / 3 = 10 are currently in training. Therefore, 15 - 10 = 5 dolphins will be trained next month. The answer is 5.
Q: Summer and Jolly both went to the same middle school. However, when they finished college, Summer had five more degrees than Jolly. If Summer has a total of 150 degrees, what's the combined number of degrees they both have?
A: Jolly has 150 - 5 = 145 degrees. Since Summer has 150 degrees, the combined total for both is 150 + 145 = 295. The answer is 295.
Question: Jessy told eleven jokes this past Saturday, and Alan told seven jokes. If they doubled the number of jokes they told this past Saturday next Saturday, how many jokes would they have told in total together so far?
Answer: This past Saturday, Jessy and Alan told a total of 11 + 7 = 18 jokes together. Since Jessy told eleven jokes this past Saturday, when he doubles the number of jokes next Saturday, the number of jokes will be 2 * 11 = 22 next Saturday. At the same time, after telling seven jokes this Saturday, when he doubles the number of jokes next Saturday, Alan will tell 2 * 7 = 14 jokes. Next Saturday, they will tell 14 + 22 = 36 jokes together. In total, the number of jokes will be 36 + 18 = 54 jokes on the two Saturdays. The answer is 54.
[Question]Kayla and Theresa went to buy some chocolate bars and soda cans. Theresa bought twice the number of chocolate bars and soda cans Kayla bought. If Theresa bought 12 chocolate bars and 18 soda cans, how many chocolate bars and soda cans did Kayla buy in total?
[Answer]Kayla bought 12 chocolate bars / 2 = 6 chocolate bars. She also bought 18 soda cans / 2 = 9 soda cans. The total number of chocolate bars and soda cans Kayla bought is 6 chocolate bars + 9 soda cans = 15 items. The answer is 15.
Q: Jennie drives to her son’s house in 5 hours when there is heavy traffic. When there is no traffic the same trip takes only 4 hours. If her son's house is 200 miles away, what is the difference between her average speed when there is heavy traffic and when there is no traffic?
A: Jennie can cover the 200 - mile distance in 5 hours when there is heavy traffic, so her average speed is 200 / 5 = 40mph. She can cover the same distance in 4 hours when there is no traffic for an average speed of 200 / 4 = 50mph. The difference in average speed between the two scenarios is (50 - 40)mph = 10mph. The answer is 10.
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:

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.

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.
