    Hey just doing an is/lm question for college just wondering could someone help me out im kind of stuck :confused:


    C = 220 + 0.75Y
    I = 165 – 10i
    G(bar) = 490
    TR(bar) = 300
    T = .15Y
    Ld = .2Y – 3i
    M(bar) = 550


    (i) Using the above data, derive the equation for the IS curve and LM curve

    It's a been a while, but I think the IS element of the equation would look like:

    Y - tY = C + I + G

    and the LM is a mix of the others. Basically for equiblirum IS must equal LM, so sort out the formula, do some algebra and find the simultaneous.

    Like I said, it's been a while, so I might be wrong.

    Check your textbook/notes.
