Consider the following data for a municipal waste collectionsystem:

Travel time, garage to route:   20 mins

Travel time, route to disposal site: 20 mins

Time to unload at disposal site:      15mins

Time from disposal site to garage: 15 mins

Time spent on worker breaks:       40mins / day

Packer truckvolume:                   25 yd^3

Compactionratio:                         4

Curb volume perservice:             0.2 yd^3 / customer

Travel time betweenstops:           30 secs

Customer served perstop:           4

Time loading perstop:                   1 min

a) How many hours per day would the crew have to work if it fillsthe truck twice per day?

b) Making two runs per day, how many customers would be served pertruck if each home has once-per-week service and the truck is usedfive days per week?

c) Suppose the cost of a crew for one truck is $40 per hour for thefirst eight hours per day, plus $60 per hour for any hours overthat amount. Assume that the crew works 52 weeks per year:Furthermore, suppose a packer truck has an annualized cost of$10,000 + 3,500 / yd^3. What would be the annual cost of service(crew plus truck) per customer?
