Homework Help: PW, FW, and AW method in engineering economy

    1. The problem statement, all variables and given/known data
    i just have a simple question. in engineering economy, when you're comparing alternatives and they don't tell you whether to use PW, FW, or AW method, can you just use any one?

    2. Relevant equations

    3. The attempt at a solution

    Welcome to the PF.

    Could you please define your acronyms and give more details? Can you give an example problem?

    PW means present worth, AW means annual worth, and FW means future worth. They're methods that allow you to compare alternatives (the greater answer is the better alternative). But it's okay, I just found out that you can in fact use any of these methods to do it. Thanks though! :)
