Q: Anna can read 1 page in 1 minute. Carole can read as fast as Anna but at half the speed of Brianna. How long does it take Brianna to read a 100-page book?
A: 50
Step-by-step reasoning process: If Anna can read 1 page in 1 minute, then her speed is 1 / 1 = 1 page per min. If Carole can read at Anna's same speed then her speed is also 1 page per min. If Carole is only half the speed of Brianna, then that means Brianna is twice as fast as Carole, so 2 * 1 page per min = 2 pages per min. If a book is 100 pages long and Brianna can read 2 pages per minute, then it will take her 100 / 2 = 50 minutes to read the book.


Q: While reading in bed with his wife Susan, Charlie heard a noise at the door. It was Sarah entering the bedroom with 4 friends. If there were also 8 people in the living room, how many people are in the house?
A: 15
Step-by-step reasoning process: In the bedroom, there are 1 + 1 = 2 people in the house (Charlie and Susan). Sarah and four friends then entered, a total of 4 + 1 = 5 people. Together with Charlie and Susan, there are now 5 + 2 = 7 people in the bedroom. Since there are 8 more people in the living room, the total number of people in the house is 8 + 7 = 15.


Q: Susie opens a pizza store. She charges $3 per slice and $15 for a whole pizza. If she was able to sell 24 slices of pizza and 3 whole pizzas, how much money did she earn?
A: 117
Step-by-step reasoning process: She was able to earn 24 x 3 = $72 after selling 24 slices. She earned 15 x 3 = $45 after selling 3 whole pizzas. Therefore, she earned a total of $72 + $45 = $117.


Q: Lana and her friends go to a theater on the weekend to watch a new play Joan told them was live. When they arrived, Lana saw 100 cars in the front parking lot. She saw two times more vehicles at the back than there were in the front parking lot. If the total number of cars at the end of the play was 700, how many more cars packed into the parking lot during the play?
A: 300

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.

Step-by-step reasoning process: The number of cars in the back parking lot was 100 * 2 = 200 times more than those in the front parking lot. There were 200 + 100 = 300 cars in the back parking lot. A total of 300 + 100 = 400 cars were present before the play began. The total number of cars that parked in the theater during the play is 700 - 400 = 300 cars.
