[Question]Mathilda is determined to pay back the money she owes a friend so she decides to pay an initial installment of $125. If she still has 75% left to pay, how much did she owe originally?
[Answer]Percentage means per 100, so if she still owes 75%, she must have paid 100% - 75% = 25% of the original amount. 25% of the original amount = (25 / 100) * original amount = $125. Multiplying both sides by (100 / 25) gives: original amount = (100 / 25) * $125 = $500. The answer is 500.

Question: Amber and Josh are flying to France for vacation. Their flight leaves at 8:00 pm and as an international flight, it's recommended that they check in 2 hours early. It will take 45 minutes to drive to the airport and another 15 minutes to park their vehicle and make their way to the terminal. What is the latest time they can leave their house to make it to the airport in time?
Answer: It will take 45 minutes to drive to the airport and 15 minutes to park so that's 45 + 15 = 60 minutes (1 hour).

Their flight leaves at 8:00 pm and it will take 3 hours to drive there and check in so the latest they can leave is 8 - 3 = 5:00 pm. The answer is 5.
