    Building a business plan?

    Guys, its me again.
    Once again professor leaving us stuff that inst on the curriculum/text book.

    need a hand here got like 10 of these to do.

    Heres one of them:

    Start a computer building business.
    *You have a $10,000 loan.
    * Max 90 hours to devote.
    *Demand of product is 3 laptops for every 1 desktop.

    To build a desktop:
    -Cost of parts:$700
    -Time: 5 hours
    -Profit: $500

    To build laptop:
    -Cost of parts: $400
    -Time: 3 hours
    -Profit: $300

    How many of each should you make to maximize profit?

    Thank you for the input.

    This problem does not seem well-formed to me.

    We start with $10,000, but by putting profits back into the business we could make an arbitrarily large number of computers over time, in theory.

    Assuming that we do not put any profits back into the business, it is unclear why we are told that the demand for laptops is three times that of desktops. Are we expecting that we might make some computers that we are unable to sell?

    If we assume additionally that every computer we make will be sold, then I think it's pretty clear that the way to maximize profits is to make 25 laptops and 0 desktops, for a profit of $7,500. But that answer seems too simple.

    If we are allowed to put profits back into the business but are limited to 90 hours total work, then any combination of laptops and desktops which uses up all 90 hours will result in the maximum profit of $9,000 -- again, assuming that all computers are sold.

    I'm really not sure what the person who made the problem was trying to ask.

    hmmm...
    yeah as ive said this professor has been giving everyone alot of trouble.

    Actually many complains about him have been filed but he doesnt care and continues to test us on things which are not relevant to our math level.

    But maybe this one will be easier to make sense.

    Will it be possible to solve when:
    *The demand is equal
    and you have a business loan of $12,400

    Hmm, the problem still doesn't seem well-formed, you've merely replaced some given values by other values without giving more information.

    This is one where I'd say, "Not enough information," or "The question is ambiguous."
