Question: John decides to learn how to play the piano. He buys a piano for $500. He then hires a teacher for 20 lessons at $40 per lesson but ends up getting a 25% discount. How much did everything cost?
Answer: The normal price of the lessons would be 20 * 40 = $800. The discount saves him 800 * .25 = $200. So the lessons cost him 800 - 200 = $600. That means everything costs 500 + 600 = $1100. The answer is 1100.

Q: Florida is starting a promotion where every car that arrives gets one orange per passenger. A family of 4 arrives and gets their oranges. They had planned to stop for a snack later where they would spend $15 in total, but now that they have the oranges they don't have to buy them at the stop. When they get to the stop they see that the oranges would've cost $1.5 each. What percentage of the money they planned to spend did they save instead?
A: The oranges would've cost $6 because 4 x 1.5 = 6. The proportion of their original spending plan was .4 because 6 / 15 = .4. They saved 40% of the money they planned to spend because .4 x 100 = 40. The answer is 40.
