Q: Jimmy needs to score at least 50 points to pass to the next class. He earned 20 points for each of the 3 exams he wrote but lost 5 points during the school year for bad behavior. How many more points can Jimmy lose and still be able to pass the next class?
A: Jimmy earned 20 * 3 = 60 points for the exams he wrote. For bad behavior, he lost 5 points, so he has 60 – 5 = 55 points left. To pass to the next class, Jimmy needs at least 50 points, so he can lose 55 – 50 = 5 more points. The answer is 5.

[Question]A machine at the soda factory can usually fill a barrel of soda in 3 minutes. However this morning a leak went unnoticed and it took 5 minutes to fill one barrel. If the leak remains undetected, how much longer will it take to fill 12 barrels of soda than on a normal day when the machine works fine?
[Answer]On a regular day it would take 3 * 12 = 36 minutes. With the leak it will take 5 * 12 = 60 minutes. It will take 60 - 36 = 24 more minutes if the leak goes undetected. The answer is 24.
Q: Danivan Drugstore has 4500 bottles of hand sanitizer gel in inventory at the beginning of the week. On Monday 2445 bottles were sold, on Tuesday 900 bottles were sold, and 50 bottles each day for the rest of the week were sold (from Wednesday until Sunday). On Saturday, the supplier delivers an order for 650 bottles. How many bottles of sanitizer gel does the Drugstore have at the end of the week?
A: The number of bottles sold on Monday and Tuesday is 2445 + 900 = 3345 bottles. Each day of the rest of the week, 50 bottles were sold, that is 5 * 50 = 250 bottles sold. Now the total of bottles sold in a week is 3345 + 250 = 3595 bottles. The drugstore has in stock 4500 – 3595 = 905 bottles. Finally the drugstore has 905 + 650 the supplier brought = 1555 bottles at the end of the week. The answer is 1555.
