PizzaRush, Inc, which is located in the general Los Angeles area, fares very well with its competition in offering fast delivery. Many students at the area universities and community colleges work part-time delivering orders made via the web at PizzaRush.com. The owner, a software engineering graduate of UPPR. plan to purchase and install five (5) portable in-car systems to increase delivery speed and accuracy. The system provides a link between the web order- placement software and On-Star system for satellite-generated directions to any address in the Los Angeles area. The expected result is faster, friendlier service to customers, and more income for PizzaRush. a Each system costs $4,600, has a 5-year useful life, and may be salvaged for an estimated $300. Total operating cost for all systems is $650 for the first year, increasing by $50 per year thereafter. The owner will not make any money inversion if he does not receive 10% or more in return.
