Can anyone tell me what is wrong with the red underlined code? Using JAVA, I'm supposed to debug this using Netbeans. This has copied copied and pasted directly from the assignment, but we haven't learned anything about lines 1, 2, 4, or 6 yet. So, I haven't the first clue if they are right or not, that's all Greek to me at this point. Also, line 32 we have learned a little bit about this, I think the operation needs to be adjusted to output a proper estimate. But it also has some weird coversion error, we haven't learned about that though either?

Thanks.
