Suppose that Marcus has the following demand curve relating the quantity demanded of electricity (measured in Kilowatt hours) to the price of electricity (measured in cents per KWH): QKWH = 1600 − 100P Marcus choose between two electricity providers with different pricing schemes. ShockCo prices electricity using a simple flat rate of $.08 per KWH. CurrentStep uses "multi-part pricing," that involves charging the same consumer different rates for additional units purchased, with the following schedule: First 100 KWH $.14 per KWH Next 200 KWH $.10 per KWH Next 200 KWH $.08 per KWH Remaining KWH $.06 per KWH
