A skilled nursing–facility chain is considering building a new facility on a piece of property that it currently owns. The property was purchased five years ago for $250,000 and could be sold now at a current market value of $100,000. When estimating the cash flows for the new facility, what amount should be included to recognize the opportunity cost of using the land for the proposed project?

a. $0 (the land is a sunk cost)
b. -$150,000
c. $250,000
d. $100,000
e. -$100,000

The monthly demand equation for an electric utility company is estimated to be p equals 60 minus left parenthesis 10 superscript negative 5 baseline right parenthesis x, where p is measured in dollars and x is measured in thousands of killowatt-hours. the utility has fixed costs of $3 comma 000 comma 000 per month and variable costs of $32 per 1000 kilowatt-hours of electricity generated, so the cost function is upper c left parenthesis x right parenthesis equals 3 times 10 superscript 6 baseline plus 32 x. (a) find the value of x and the corresponding price for 1000 kilowatt-hours that maximize the utility's profit. (b) suppose that the rising fuel costs increase the utility's variable costs from $32 to $38, so its new cost function is upper c 1 left parenthesis x right parenthesis equals 3 times 10 superscript 6 baseline plus 38 x. should the utility pass all this increase of $6 per thousand kilowatt-hours on to the consumers?
