You have been asked to analyze the queue for registrations for a popular MSOM seminar at a major national conference. Conference attendees arrive to register at the rate of 5 people every 15 minutes (Poisson distributed). It takes each host, any number of which can be hired directly through the conference at the cost of $17 per hour, 7 minutes to register a guest, following a negative exponential distribution. The conference recognizes a waiting cost of $40 per hour per guest in line. A single waiting line is set up, but can accommodate multiple servers. What is the minimum number of hosts that could be hired for this system? hosts
What is the optimal number of servers needed to minimize total costs? hosts
Rounded to the nearest dollar, what is total cost for the system (including waiting and service costs) at the optimal number of servers if the registration desk is open for an 8 hour day?
At the optimal number of servers, what is the average time a guest would spend waiting to register?

Afirm's before-tax cost of debt, rd, is the interest rate that the firm must pay on debt. because interest is tax deductible, the relevant cost of debt used to calculate a firm's wacc is the cost of debt, rd (1 – t). the cost of debt is used in calculating the wacc because we are interested in maximizing the value of the firm's stock, and the stock price depends on cash flows. it is important to emphasize that the cost of debt is the interest rate on debt, not debt because our primary concern with the cost of capital is its use in capital budgeting decisions. the rate at which the firm has borrowed in the past is because we need to know the cost of capital. for these reasons, the on outstanding debt (which reflects current market conditions) is a better measure of the cost of debt than the . the on the company's -term debt is generally used to calculate the cost of debt because more often than not, the capital is being raised to fund -term projects. quantitative problem: 5 years ago, barton industries issued 25-year noncallable, semiannual bonds with a $1,600 face value and a 8% coupon, semiannual payment ($64 payment every 6 months). the bonds currently sell for $845.87. if the firm's marginal tax rate is 40%, what is the firm's after-tax cost of debt? round your answer to 2 decimal places. do not round intermediate calcu
