It is estimated that the annual sales of an energy saving device will be 20,000 the first year and increase by 10,000 per year unitl 50,000 units are sold during the fourth year. Proposal A is to purchase manufacturing equipment costing $120,000 with an estimated salvage value of $15,000 at the end of 4 years. Proposal B is to purchase equipment costing $280,000 with an estimated salvage value of $32,000 at the end of 4 years. The variable manufacturing cost per unit under proposal A is estimated to be $8,00, but is estimated to be only $2.60 under proposal B. If the interest rate is 9%, which proposal should be accepted for a 4-year production horizon?

Upscale hotels in the united states recently cut their prices by 20 percent in an effort to bolster dwindling occupancy rates among business travelers. a survey performed by a major research organization indicated that businesses are wary of current economic conditions and are now resorting to electronic media, such as the internet and the telephone, to transact business. assume a company's budget permits it to spend $5,000 per month on either business travel or electronic media to transact business. graphically illustrate how a 20 percent decline in the price of business travel would impact this company's budget set if the price of business travel was initially $1,000 per trip and the price of electronic media was $500 per hour. suppose that, after the price of business travel drops, the company issues a report indicating that its marginal rate of substitution between electronic media and business travel is 1. is the company allocating resources efficiently? explain.

Power plants that rely on coal increase the amount of sulfur dioxide that dissolves into the air, eventually increasing the acidity of precipitation. the higher acidity of rain and snow can damage forests by making it more difficult for plants to absorb minerals from the soil. the equations below provide information about the market demand and supply of electricity. there is a constant marginal external cost of $25 per unit of electricity.d: qd= 200 – 2ps: qs=p – 10what quantity of electricity satisfies allocative efficiency in this market? a. 60b. 70c. 50d. 43.3
