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?
what is the optimal number of servers needed to minimize total costs?
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?

Dahlia enterprises needs someone to supply it with 127,000 cartons of machine screws per year to support its manufacturing needs over the next five years, and you’ve decided to bid on the contract. it will cost you $940,000 to install the equipment necessary to start production; you’ll depreciate this cost straight-line to zero over the project’s life. you estimate that in five years, this equipment can be salvaged for $77,000. your fixed production costs will be $332,000 per year, and your variable production costs should be $11.00 per carton. you also need an initial investment in net working capital of $82,000. if your tax rate is 30 percent and your required return is 11 percent on your investment, what bid price should you submit? (do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))
