Draw an indifference map for a typical person’s preferences over five-dollar bills and ten- dollar bills using the vertical axis for five-dollar bills and the horizontal axis for ten-dollar bills. What is the marginal rate of substitution (MRS)?

Investment x offers to pay you $5,700 per year for 9 years, whereas investment y offers to pay you $8,300 per year for 5 years. if the discount rate is 6 percent, what is the present value of these cash flows? (do not round intermediate calculations and round your answers to 2 decimal places, e. g., 32.16.) present value investment x $ investment y $ if the discount rate is 16 percent, what is the present value of these cash flows?

Suppose either computers or televisions can be assembled with the following labor inputs: units produced 1 2 3 4 5 6 7 8 9 10 total labor used 3 7 12 18 25 33 42 54 70 90 (a) draw the production possibilities curve for an economy with 54 units of labor. label it p54. (b) what is the opportunity cost of the eighth computer? (c) suppose immigration brings in 36 more workers. redraw the production possibilities curve to reflect this added labor. label the new curve p90.

White truffles are a very prized and rare edible fungus that grow naturally in the countryside near alba, italy. suppose that it costs $200 per day to search for white truffles. on an average day, the total number of white truffles (t) found in alba is t = 20x − x 2 , where x is the number of people searching for white truffles on that day. white truffles can be sold for $100 each. if there is no regulation, how many more people will be searching for white truffles than the socially optimal number?
