Why are you suggesting that I can not read the problem?

So what is the final answer? I do not want you to show me how to do the problem, I am simply asking for the correct answer.

I apologize but I cannot transfer all my work on paper on to this computer so it would be helpful if you could just tell me the answer so when I finish solving the problem, I will be able to check it to see if it is correct.

I am most definitely not using this is a cheating site! I would never do that! I just wanted to have an answer for the question to check if i did the question properly

Why can I not use latex? Please just help me with the problem, Melody
