The estimated cost of a completely installed and ready-to-operate 40-kilowatt generator is $32,000. its annual maintenance costs are estimated at $800. the energy that can be generated annually at full load is estimated to be 100,000 kilowatt-hours. if the value of the energy generated is $0.09 per kilowatt-hour, how long will it take before the machine becomes profitable? take the marr to be 10% and the salvage value of the machine to be $2,000 at the end of its estimated life of 15 years.

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
