[Question]Nick's cell phone was initially empty but was then charged for 45 minutes and has reached a 25% charge. How much longer must the cell phone be charged to reach 100% charge?
[Answer]The ratio between the time charged and the time to be charged is 100 / 25 = 4. To reach 100%, the cell must be charged for 45 minutes * 4 = 180 minutes. Subtracting the 45 minutes that Jimmy already used to charge the cell phone, there are still 180 - 45 = 135 minutes of charging time left. The answer is 135.

Q: Tom fills a 250 pound sandbag 80% full. But the filling material he is using is 40% heavier than sand. How much does the bag weigh?
A: The bag full of sand would weigh 250 * .8 = 200 pounds. The filling material would make it 200 * .4 = 80 pounds heavier. So it weighs 200 + 80 = 280 pounds. The answer is 280.
Question: There are 32 tables in a hall. Half the tables have 2 chairs each, 5 have 3 chairs each and the rest have 4 chairs each. How many chairs in total are in the hall?
Answer:
Half of 32 tables is 32 * (1 / 2) = 16 tables. 16 tables have 2 chairs each for a total of 16 * 2 = 32 chairs. 5 tables have 3 chairs each for a total of 5 * 3 = 15 chairs. There are 32 - (16 + 5) = 11 tables left. 11 tables have 4 chairs each for a total of 11 * 4 = 44 chairs. The total number of chairs is 32 + 15 + 44 = 91 chairs. The answer is 91.
