    if it takes 7 people, 2 days to do a job

    how many people would it take to do that job in half a day?

    7 x 12?

    If it takes 7 people 2 days to do the job, assuming all people are the same, it would take 14 people to do it in 1 day. So, it should take 28 people to do it in half a day...assuming that it's physically possible to do the job in half a day.

    Divide the 2 days in 4 halves and multiply by 7.

    Just for future reference Bob, this is how you can figure a problem like this out, regardless of the time or the amount of people.

    You have the variables of # of people and of time, set to equal 1 job.

    So, your basic equation looks like this:

    (# people)(time) = 1 job

    or

    (P)(T) = J

    In the problem, you are given a P and a T value.

    (7)(2) = J
    (7)(2) = 14

    Now, since you know the "value" of a completed job, any further combination of variables must equal 14.

    In the second part of the problem you are given only one of the variables, amount of time.

    (P)(.5) = 14
    (28)(.5) = 14

    What, no accounting for efficiencies arising from economies of scale and division of labor?

    I just assumed a Marxist society where labor divisions would be set up for maximum efficiency. Much like the government retooling of our auto-industry...or something.

    1/2 a day is a 1/4 of 2 days.....so 4 is the multiplier. 4 x 7 = 28?

    The real question is how many CowboysZone forum posters would it take to do that same job in 2 days?

    I'm not sure of the answer, but I do know that if Yeager is part of the work force, you have a one week penalty right off the bat. :laugh2:

    Unlikely. You would be surprised how often people use Algebra everyday without even noticing it.

    I aced trig, even had my math teacher persuade me to take AP Calculus

    but for the life of me I was stumped trying to get through proofs, I think I eeked out a D in Geometry

    :lmao2: so true
