I'm sorry I was wrong. Can you show me how you got 20%?
Aaarrgghh! I had a brain malfunction! I see what I did wrong.
15/75 = 0.2 = 20%
I found on the rare occasions that I taught math that I was only about 95% accurate. I was embarrassed, but told my students that I'd give them extra credit if they found an error that I made on the board and politely told me about it.

Don't feel bad for yourself Ms. Sue! You are an awesome teacher. It's me, I should be really learning more into this subject. =)
Thank you. :-)

The answer would be 15% because if you already add 1 to 75 it turns to an 85 plus another 5 it would now be a 90%
