Answer this question:The time Juan takes to grab his lunch from his office and back is half the time he takes to read a book. If he has a 4000-page book, how many pages does he read in an hour if he takes 4 hours to move from his office to grab lunch?
If Juan takes 4 hours to move from his office to grab lunch, moving from his office and back takes 2 * 4 = 8 hours. The time Juan takes to grab his lunch from his office and back is half the time he takes to read a book, meaning he reads a book in 8 * 2 = 16 hours. If he has a 4000 - page book, he will read 4000 / 16 = 250 pages in an hour.
The answer is 250.

Answer this question:Carrie wants to take a trip to New York. She can get a 20% discount on an $850 flight with Delta Airlines. She can also save 30% off an $1100 flight with United Airlines. How much money would she save by choosing the cheapest flight?
The discount for the Delta flight would come to $850 * 0.20 = $170. The final price of the Delta flight would come to $850 - $170 = $680. The discount of the United flight would come to $1100 * 0.30 = $330. The final price of the United flight would come to $1100 - $330 = $770. The Delta flight would be cheaper than the United flight by $770 - $680 = $90.
The answer is 90.

Answer this question:Grace is looking to plant some lettuce in her raised bed garden. Her raised bed is comprised of 2 large beds on top with 2 medium beds on the bottom. The top bed can hold 4 rows of lettuce with 25 seeds being sown per row. The medium bed can house 3 rows with 20 seeds being sown per row. How many seeds can Grace plant in all four beds of her raised bed garden?
A large bed can hold 4 rows with 25 seeds per row, 4 * 25 = 100 seeds per large bed. 100 seeds per large bed and there are 2 beds, 100 * 2 = 200 seeds needed in total for both large beds. A medium bed can hold 3 rows with 20 seeds sown per row, 3 * 20 = 60 seeds per medium bed. 60 seeds per medium bed and there are 2 medium beds, 60 * 2 = 120 seeds needed in total for both medium beds. 200 seeds needed for the large beds combined with 120 seeds needed for the medium beds comes to 200 + 120 = 320 seeds needed to plant all four beds of the raised garden bed.
The answer is 320.
