Part A) Joe Zingga needs to figure out what software to use for his new commercial website. After a bit of research he has narrowed his choices down to either an Apache or Microsoft web server. Joe expects a high hit rate of 90 hits per minute and estimates earning 1.5 cents per hit on average. The Microsoft server will have a down time of 4 hours per week and the Apache one will only have a downtime of 0.75 hours per week. Joe's sister Josephine is very familiar with the Windows system, as she uses it at her own place of work, and she has offered to help, so Joe estimates that he will have no maintenance costs if he decides to go with the Microsoft system. If he decides on the Apache web server he will have to pay for yearly fees & training costs of $5,000 per year. Which web server should he install to maximize his profit? Do not worry about leap-years and assume that there are exactly 365 days per year. Part B) Joe's entrepreneurial venture has started off well and production is going smoothly. The workers he hired are becoming familiar with the manufacture of the product and he expects that the current rate of learning will continue, with the manufacture of future units becoming more efficient and taking less time per unit. The first unit took his team 500 hours to produce and the second one only took 425 hours to make. 1) At what rate is learning occurring? 2) How long will it take to produce the fourth unit? 3) If he pays his workers $15 per hour, what is the cumulative average labour cost per unit for the first four units produced
