Question: James goes out to eat. He orders a steak and egg meal for $16. He is with his friend, who orders chicken fried steak for $14. His friend pays for half the bill and James pays the tip along with his half of the bill. They tip 20%. How much did James pay?
Answer: The meals cost 16 + 14 = $30. So each paid 30 / 2 = $15. James left a tip of 30 * .2 = $6. So James paid 15 + 6 = $21. The answer is 21.
[Question]Ginger is weaving mats out of colored straw. Each mat takes 20 red straws, 30 orange straws, and half as many green straws as orange straws. How many straws does she need to make 10 mats?
[Answer]First find the number of green straws each mat needs: 30 orange straws / 2 orange straws / green straw = 15 green straws. Then find the total number of straws in each mat: 15 straws + 20 straws + 30 straws = 65 straws. Then multiply that number by the number of mats to find the total number of straws Ginger needs: 65 straws / mat * 10 mats = 650 straws. The answer is 650.
Q: Debra is the host of a country music radio show, and she broadcasts interviews with celebrity country music singers. Each week, she interviews three singers, one at a time. The first interview segment is always twice as long as the other two segments combined, and the third interview segment is always half as long as the second. If the third segment is 10 minutes long, how many minutes long is the entire show?
A: If the third segment is half as long as the second, then the second segment is twice as long as the third, or 10 * 2 = 20 minutes long. The first segment is twice as long as the other two combined, or 2 * (10 + 20) = 60 minutes. Thus, in total, the show is 10 + 20 + 60 = 90 minutes long. The answer is 90.
Question: Eden's mom is twice as old as Eden, who is twice as old as Devin. If Devin is 12 years old, what's the average age of the three?
Answer: If Devin is 12 years old, then Eden is 2 * 12 years = 24 years old. Since Eden's mom two times older than Eden, her age is 24 years * 2 = 48 years. In total, they have 48 years + 24 years + 12 years = 84 years. The average age for the three is 84 years / 3 people = 28 years / person. The answer is 28.
[Question]Joshua and Justin shared $40. Joshua’s share was thrice as much as Justin’s. How much is Joshua's share?
[Answer]The $40 is divided into 1 part for Justin + 3 parts for Joshua = 4 parts. So each part is equal to $40 / 4 = $10. Therefore, Joshua's share is $10 x 3 = $30. The answer is 30.
[Question]Rex is taking lessons for his driver’s license. He wants to take 40 hour-long lessons before his test, and decides to have two-hour sessions twice a week until he has done his test. After 6 weeks, how many more weeks will Rex need to continue taking lessons to reach his goal?
[Answer]
Each week, Rex is taking 2 hour - long lessons * 2 times a week = 4 lessons. After 6 weeks, he has done 4 lessons per week * 6 weeks = 24 lessons. So Rex still needs 40 total lessons – 24 lessons taken = 16 lessons. He will therefore need lessons for another 16 lessons / 4 lessons per week = 4 weeks. The answer is 4.
