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?
Please answer and provide answer explanation.
1100
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.

.

So, the answer is 1100
