The owner of Atlantic City Confectionary is considering the purchase of a new semiautomatic candy machine. The machine will cost $23,000 and last 10 years. The machine is expected to have no salvage value at the end of its useful life. The owner projects that the new candy machine will generate $4,600 in after-tax savings each year during its life (including the depreciation tax shield). Use Appendix A for your reference. (Use appropriate factor(s) from the tables provided.)
Required:
Compute the profitability index on the proposed candy machine, assuming an after-tax hurdle rate of: (a) 8 percent, (b) 10 percent, and (c) 12 percent. (Round your final answers to 2 decimal places.)

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?
