Fast-track is the train system that serves the state of Wonderland. The firm’s cost, revenue, and demand information are given below. Based on the table, complete the table and the following three regulation scenarios: Cost and revenue for Fast-track Q (million of riders) Price (P) Total Cost (million $) Total Revenue (million $) Marginal Cost (MC) Marginal Revenue (MR) Average Cost (AC) 1 30 20 30 — [option2] 20 2 26 38 52 18 22 19 3 23.3 54 69.9 16 17.9 18 4 21 68 84 [option1] 14.1 17 5 18 80 90 12 6 [option3] 6 15 90 90 10 0 15 7 10 98 70 8 -20 14 8 6 104 48 6 -22 13 A profit-maximizing unregulated natural monopoly will produce at the quantity where [option4], hence charging [option5] and having a profit of 160.  If the government decides to regulate this natural monopoly by forcing them to produce at the point where the demand curve intersects the marginal cost, or at [option6], then the firm would have [option7]. If the government decides to regulate this natural monopoly by forcing them to sell the quantity and charge the price where the market demand curve crosses the average cost curve, the quantity would be [option8], the market price would be [option9], and this firm will [option10].  The best regulatory choice is [option11] because the firm [option12].

Consider the diagram above in which a current I flows to the right. Point P is directly above the wire and point Q is directly below it. If a proton were at point Q and traveling straight down the page, away from the wire, the magnetic force on it would be in which direction?

A local lawncare service is contemplating replacing an older leaf collector/shredder with a new more powerful unit.  While the old unit works, employees frequently complain about how easily the existing unit clogs, constant breakdowns, and how noisy it is.  A new unit is expected to solve all of these problems.  However, because the leaf collector/shredder is only used for 2 months a year, the lawncare service’s owner is uncertain if buying the new unit is sensible.   Repairing the existing unit requires an average of ${fi} for the year and the operating costs are ${vi} an hour when it is working.  A new unit can be leased for ${fo} per year and will cost ${vo} per hour to operate.  What is the crossover point in hours for these 2 options?
