Question 860383
@richwmiller This site is to answer to people's problems and share our solutions with them, but definitely NOT correct their mistakes or make irrelevant and off topic answers regarding their math problem. You chose the wrong site to do that. A lot of your answers are actually like that and probably that's why your number of answers is that high. You forgot the ending "-ed" at the word "call", by the way. I wanted to act like you did. Sorry. Couldn't help it.

Regarding the OP now, you can look up here for an answer: #860623 .
A tutor was willing to help you with your problem even though you posted it twice. 

Good luck with your homework!
