P(250)=20000.2(250)0.01(250)2=1325P(250)=2000-0.2*(250)-0.01*(250)^2=1325

The consumer surplus is as follows

0250(p(x)P)dx=0250(20000.2x0.01x21325)dx=[675x0.1x20.01x33]0250=6752500.01(250)20.01(250)33=110416.67\int_0^{250}(p(x)-P)dx=\int_0^{250}(2000-0.2x-0.01x^2-1325)dx=[675x-0.1x^2-\frac{0.01x^3}{3}]|_0^{250}=675*250-0.01*(250)^2-\frac{0.01*(250)^3}{3}=110416.67
