Amathematical approximation called the rule of 70 tells us that the number of years that it will take something that is growing to double in size is approximately equal to the number 70 divided by its percentage rate of growth. thus, if mexico's real gdp per person is growing at 7 percent per year, it will take about 10 years(=70/7) to double. apply the rule of 70 to solve the following problem. real gdp per person in mexico in 2005 was about $11,000 per person, while it was about $44,000 per person in the u.s. if real gdp per person in mexico grows at the rate of 5 percent per year: how long will it take mexico's real gdp per person to reach the level that the united states was at in 2005? (hint: how many times would mexico's 2005 real gdp per person have to double to reach the u.s.'s 2005 real gdp per person?

Consider the local telephone company, a natural monopoly. the following graph shows the monthly demand curve for phone services and the company’s marginal revenue (mr), marginal cost (mc), and average total cost (atc) curves. 0 2 4 6 8 10 12 14 16 18 20 100 90 80 70 60 50 40 30 20 10 0 price (dollars per subscription) quantity (thousands of subscriptions) d mr mc atc 8, 60 suppose that the government has decided not to regulate this industry, and the firm is free to maximize profits, without constraints. complete the first row of the following table. pricing mechanism short run long-run decision quantity price profit (subscriptions) (dollars per subscription) profit maximization marginal-cost pricing average-cost pricing suppose that the government forces the monopolist to set the price equal to marginal cost. complete the second row of the previous table. suppose that the government forces the monopolist to set the price equal to average total cost. complete the third row of the previous table. under average-cost pricing, the government will raise the price of output whenever a firm’s costs increase, and lower the price whenever a firm’s costs decrease. over time, under the average-cost pricing policy, what will the local telephone company most likely do

Uppose that the federal reserve purchases a bond for $100,000 from donald truck, who deposits the proceeds in the manufacturer’s national bank. what will be the impact of this purchase on the supply of money? the money supply will increase by $100,000. the money supply will increase by $80,000. the money supply will increase by $500,000. this action will have no effect on the money supply. if the reserve requirement ratio is 20 percent, what is the maximum amount of additional loans that the manufacturer’s bank will be able to extend as the result of truck’s deposit? the maximum additional loans is $100,000. the maximum additional loans is $80,000. the maximum additional loans is $20,000. the maximum additional loans is $500,000. given the 20 percent reserve requirement, what is the maximum increase in the quantity of checkable deposits that could result throughout the entire banking system because of the fed’s action? this action will have no effect on the money supply. the money supply will eventually increase by $80,000. the money supply will eventually increase by $500,000. the money supply will eventually increase by $100,000.
