calculate the reverse demand and consumer surplus at price p = 10 dollars, as well as the graphical representation for each case a) D(p) = 100 p. b) D(p) = 100 bp ( where b is a positive constant ) c) D(p) = 100 0.25p. d) D(p) = a p ( a is a positive constant ) 2- The price goes from 10 to 13 dollars
