A: 20%
B: 16.7%
C: 8.3%
D: 15%

Hi Ms. Sue, it was 20%. Thank you for your help, though! You are still my favorite website to go on! =)

Answer 1

I'm sorry I was wrong. Can you show me how you got 20%?

Answer 2

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.

Answer 3

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. =)
