    logs supply and demand

    Qd=60-18log p
    qs=-40+32log p
    60-18logp = 40+32log p
    100=18 log p + 32 log p
    100= 50 log p
    2= log p
    p= 10^2=100
    Q= 24


    how did they get 24?
    lol no problem doh

    Disclaimer: I don't know anything about 'Business Math'.

    However, could it be the following:
    You calculate that p= 10^2=100

    So could Q= 24 be a typing error? Shouldn't it be Qd= 24 ? This because:
    Qd=60-18log p
    Qd=60-18log 100=24

    But than again, I don't know what Qd or Qs stands for so I could be completely wrong
