1- In the following cases, calculate the inverse demand and consumer surplus at price p = 10 dollars, as well as the graphical representation. 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, where a is a positive constant. 2- The price increases from $10 to $13
