Each power plant can supply the following numbers of kilowatt-hours (kwh) of electricity: plant 1, 35 million; plant 2, 50 million; plant 3, 40 million. The peak power demands in these cities, which occur at the same time (2:00 P.M.), are as follows (in kwh): city A, 20 million; city B, 20 million; city C, 30 million; city D, 30 million.

Example Suppose that the economy of the city of Everett depends on three industries Logging-timber operation, electricity and aircraft-manufacturing plant. Monitoring the operations of these three industries over a period of one year, we were able to come up with the following observations: 1. To produce 1 unit worth of timber, the Logging-timber industry must consume 0.3 units of its own production, 0.3 units of electricisy and 0.3 units of aircraft to run its operations 2. To produce 1 unit...

You have just bought out your only competitor in the region for the supply of electrical power. With the acquisition you now have a second power generation plant (Q2), but one that operates slightly differently to the one you already had (Q1). Both power plants will generate an identical electrical product (voltage and frequency) and can be combined to supply the market, i.e. QT otal = Q1 + Q2. The inverse demand function you are faced with can be represented...
