Aremotely located air sampling station can be powered by solar cells or by running an electric line to the site and using conventional power. solar cells will cost $12,600 to install and will have a useful life of 4 years with no salvage value. annual costs for inspection, cleaning, etc., are expected to be $1400. a new power line will cost $11,000 to install, with power costs expected to be $800 per year. since the air sampling project will end in 4 years, the salvage value of the line is considered to be zero. at an interest rate of 10% per year, which alternative should be selected on the basis of a future worth analysis?

Because this market is a monopolistically competitive market, you can tell that it is in long-run equilibrium by the fact thatmr=mc at the optimal quantity for each firm. furthermore, a monopolistically competitive firm's average total cost in long-run equilibrium isless than the minimum average total cost. true or false: this indicates that there is a markup on marginal cost in the market for engines. true false monopolistic competition may also be socially inefficient because there are too many or too few firms in the market. the presence of the externality implies that there is too little entry of new firms in the market.

Almeda products, inc., uses a job-order costing system. the company's inventory balances on april 1, the start of its fiscal year, were as follows:

Ahospital purchases a $500,000 magnetic resonance imaging (mri) machine that has a useful life of 9 years. the salvage value at the end of 9 years is $77,000. (a) write a linear equation that describes the value y (in dollars) of the mri machine in terms of the time t (in years), 0 ≤ t ≤ 9. (b) find the value, in dollars, of the machine after 6 years. $ (c) find the time, in years, when the value of the equipment will be $140,000. (round your answer to two decimal places.) yr
