The following are the sample data sets from your class project about waiting line theories:
arrival: 1, 3, 3, 3, 4
service time: 33, 33, 52, 69, 58
the arrival data were number of cars arrived per every 5-minute interval, and the service data were the number of seconds spent on taking the corresponding order. what is the expected total number of customers (cs) in the store for a given 5-minute interval? give your answer to 2 significant places.

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))
