The manager is concerned that, despite the fact that the firm’s competitors are comparatively small, collectively their annual revenue growth has exceeded 50 percent over each of the last five years. She has requested that the value projections be based on the firm’s current profits of \$4.4 billion (which have yet to be paid out to stockholders) and the average interest rate over the past 20 years (9 percent) in each of the following profit growth scenarios:

a. Profits grow at an annual rate of 10 percent. (This one is tricky.)
The firm will shut down at its growth rateThe growth rate is not possibleThe firms value is infiniteThe firms value is zeroInstructions: Round your responses to 2 decimal places.b. Profits grow at an annual rate of 3 percent.billionc. Profits grow at an annual rate of 0 percent.billiond. Profits decline at an annual rate of 2 percent.billion A firm produces output according to a production function:

Q = F(K,L) = min {9K,3L}.

a. How much output is produced when K = 2 and L = 3?

b. If the wage rate is \$70 per hour and the rental rate on capital is \$45 per hour, what is the cost-minimizing input mix for producing 9 units of output?

Capital:
Labor:

c. How does your answer to part b change if the wage rate decreases to \$45 per hour but the rental rate on capital remains at \$45 per hour?

Capital increases and labor decreases.

Capital and labor increase.

Capital decreases and labor increases.

It does not change.

From California to New York, legislative bodies across the United States are considering eliminating or reducing the surcharges that banks impose on noncustomers, who make \$10 million in withdrawals from other banks’ ATM machines. On average, noncustomers earn a wage of \$20 per hour and pay ATM fees of \$2.75 per transaction. It is estimated that banks would be willing to maintain services for 4 million transactions at \$0.75 per transaction, while noncustomers would attempt to conduct 16 million transactions at that price. Estimates suggest that, for every 1 million gap between the desired and available transactions, a typical consumer will have to spend an extra minute traveling to another machine to withdraw cash.Based on this information, what would be the nonpecuniary cost of legislation that would place a \$0.75 cap on the fees banks can charge for noncustomer transactions?Instructions: Round your answer to the nearest penny (2 decimal places). \$What would be the full economic price of this legislation?
