Question: Amanda's car takes five fewer minutes to complete the same trip to the beach than the bus. If the bus takes 40 minutes to drive 80 miles to the beach, how many minutes will it take the car to make a round trip?
Answer: If the bus takes 40 minutes to complete 80 miles of a trip, Amanda's car, which takes five fewer minutes to complete a trip than the bus, will take 40 - 5 = 35 minutes to complete the trip. A round trip will take the car twice the time for going one way, a total of 35 + 35 = 70. The answer is 70.

Question: There are 10 books on the table. Two-fifths of them are reading books and three-tenths of them are math books. There is one fewer science book than math books and the rest are history books. How many history books are there?
Answer: Out of the 10 books, 10 x 2 / 5 = 4 are reading books. While 10 x 3 / 10 = 3 are math books. There are 3 - 1 = 2 science books. So, the total number of reading, math, and science books is 4 + 3 + 2 = 9. Thus, there is only 10 - 9 = 1 history book. The answer is 1.

[Question]Jimmy and Irene go shopping for clothes on a Tuesday, where senior citizens get a 10% discount on their purchases. Jimmy picks out 3 shorts from the $15 rack. Irene grabs 5 shirts from the $17 rack. How much money do they give to the cashier?
[Answer]
Jimmy's shorts cost 3 x $15 = $45. Irene's shirts cost 5 x $17 = $85. Total cost for the clothes is $45 + $85 = $130. 10% discount on the clothes is $130 x 10% = $13. They give the cashier $130 - $13 = $117. The answer is 117.
