    I have the following circuit attached. Including the problem and solution. for some reason, I either can't plot it in LTSpice correctly to verify the answer, or my answer is incorrect. Would someone help please?

    For some reason I can't look at your schematic. Can you use a different file type to post it? Even Paint will create a viewable JPEG file.

    Hmm, if I remember well the voltage gain is equal:
    Au=gm*Rc1:
    105=21.1mS*Rc1--->Rc1=4.97K=5.1K
