Question

Suppose the demand function for a product is given by the function:
D(q)=-0.01 q + 23
Use integration (or other appropriate methods) to find the Consumer's Surplus corresponding to q=1,200 units.
(Do no rounding of results until the very end of your calculations. At that point, round to the nearest tenth, if necessary. It may help you to sketch the demand curve, which crosses the horizontal at q=2,300.)
