Can someone explain LIFO

This goes for all your posts. We are not here to just do your homework for you. You need to make an attempt to do your own homework and someone here can check your work, give further hints, etc. Or just ask what thing you don't understand.

Homework should also be directed over to Homework Help under Education, as the big red announcement at the top of the page says.

Well, if I knew for sure how to do the LIFO then I wouldn't need to ask now would I? You don't know me and I don't know you so it is best that you leave me alone. I don't know why you are trying to offend me or threaten me because I am new to this website but it won't work. Please don't respond to any of my questions. You leave me alone and I will not respond to your no help. I would prefer someone with something important to say. Goodbye.

First of all, your original question had a homework problem on it. You've obviously edited it. If you'd merely asked a general question about LIFO I would have answered it.

Second, we have rules around here. I was stating the rules for you. Is this how you react at school when an instructor asks you to follow the instructions? If you interpret this as being offensive, you are the one with the issues. And the very idea that I posted that in order to THREATEN you??

Wow, you are one paranoid person with some issues.
