Suppose the inverse demand curve on ore is given by P = 77 - 0.42 Q. Ore can be either mined or obtained through a recycling program. The marginal cost of mining is MC1 = 7 q1. The marginal cost of obtaining ore through recycling is MC2 = 12 + 3 q2. What percent of total demand is

A university spent $1.6 million to install solar panels atop a parking garage. These panels will have a capacity of 700 kilowatts (kW) and have a life expectancy of 20 years. Suppose that the discount rate is 20%, that electricity can be purchased at $0.30 per kilowatt-hour (kWh), and that the marginal cost of electricity production using the solar panels is zero. Hint: It may be easier to think of the present value of operating the solar panels for 1 hour per year first. Approximately how many hours per year will the solar panels need to operate to enable this project to break even? 1,564.62   2,503.39   625.85     If the solar panels can operate only for 1,408 hours a year at maximum, the projectwould   break even.   Continue to assume that the solar panels can operate only for 1,408 hours a year at maximum. In order for the project to be worthwhile (i.e., at least break even), the university would need a grant of at least

Suppose that the demand curve for tickets to see a football team is given by Q = 36,000 - 4p and marginal cost = 1000 per customer. (Ten dollars as this is expressed in pennies) This can also be written as D(P) = 9000 -0.25 Q. MR = 9000-0.5 Q Suppose there are only 45,000 seats in the stadium. We would like for you to solve for the PRICE (in dollars) that the PROFIT MAXIMIZING UNREGULATED MONOPOLIST would charge. $30 O $90 $60 $50 O $70

The Lead Zeppelin Company produces powered and steerable lighter-than-air craft. The company’s airships are specially lined and are therefore safer than normal dirigibles. The table below shows the weekly production of dirigibles, along with the associated Average Cost and Total Revenue figures (the Average Cost and Total Revenue figures are actually in thousands of dollars, so the $15 represents $15,000, but we have left off the zeros to save space).   Quantity Average Cost Total Cost Total Revenue 0  -- 0 $0 1 $15 15 $10 2 $9 18 $20 3 $8 24 $30 4 $8.50 34 $40 5 $9 45 $50 6 $10 60 $60 7 $12 84 $70   The Lead Zeppelin Company has decided that it will produce at least 1 dirigible. Now the question becomes, how many more dirigibles should it produce to make as much profit as possible?   Use the profit-maximizing rule to explain how many dirigibles the Lead Zeppelin Company should produce to…

You hired a mathematician (who never took a Natural Resource Economics class) to solve a 4 period nonrenewable resource problem assuming a competitive industry and a total resource constraint of 100. He returns an answer to you where per period output levels are increasing and he gets a lambda value: 1 = -3.45. From this you conclude: Demand is too low for the constraint of 100 to be binding. Therefore there is no scarcity. The mathematician must have made a mathematical mistake. Competitive firms place no weight on the future and therefore behave like there is no opportunity cost of extracting a resource today. Demand is too high to support the extraction of the resource so the marginal user cost become negative.

Was it ethically acceptable for president regan to fire the striking air traffic controller?

Air Canada announces a 15% off sale on its flights, so fans can watch Toronto Raptors play against the Golden State Warriors in the NBA Finals. What effect will this sale have on Air Canada's flights to destinations other than Canada?
