The annual benefits of $4000 every year for three years may be obtained for an investment on a production equipment costing $20,000 with a salvage value of $5,000. If MARR is 6%, choose the right equation to determine the NPW. A) NPW = 20,000(F/P,6%,3) + 4,000(F/A, ^%, 3) + 5000B) NPW = -20000 + 4000(P/A,6%,3) + 5000(P/F,6%,3)C) NPW = 20,000(P/F,6%,3) + 4000(F/A,6%,3) + 5000D) -20000(P/F,6%,3) +4000(P/A,6%,3) + 5000(P/F,6%,3)

At cooly cola, we are testing the appeal of our new diet one cola. in a taste test of 250 randomly chosen cola drinkers, 200 consumers preferred diet one cola to the leading brand. assuming that the sample were large enough, the large-sample 95% confidence interval for the population proportion of cola drinkers that prefer diet one cola would be:

Suppose there are three types of consumers who attend concerts at your university’s performing arts center: students, staff, and faculty. each of these groups has a different willingness to pay for tickets; within each group, willingness to pay is identical. there is a fixed cost of $1,000 to put on a concert, but there are essentially no variable costs. for each concert: i. there are 140 students willing to pay $20. (ii) there are 200 staff members willing to pay $35. (iii) there are 100 faculty members willing to pay $50. a) if the performing arts center can charge only one price, what price should it charge? what are profits at this price? b) if the performing arts center can price discriminate and charge two prices, one for students and another for faculty/staff, what are its profits? c) if the performing arts center can perfectly price discriminate and charge students, staff, and faculty three separate prices, what are its profits?

The common stock and debt of northern sludge are valued at $65 million and $35 million, respectively. investors currently require a return of 15.9% on the common stock and a return of 7.8% on the debt. if northern sludge issues an additional $14 million of common stock and uses this money to retire debt, what happens to the expected return on the stock? assume that the change in capital structure does not affect the interest rate on northern’s debt and that there are no taxes.
