  • Hi, I have Qs=2p and Qd=9-p. I get confused because when I solve for producer surplus and set 2p=0... of course, p=0. What am I doing wrong ?

    The Q then asks if the government sets a price floor of 7, how big is the consumer/producer surplus. How much does the gov't spend?

    Any help pls?

    Qd = 100- 2P

    Qd is the linear demand line. We want to know the price when demand is at 0, so we set Qd to 0.

    0 = 100-2P

    Solve for P.

    2P = 100.

    P=50. So the price on the vertical axis when Qd is 0 is 15. This is the maximum price consumers are willing to pay.
