Problem 6-6 (Algo) Lazer Technologies Incorporated (LTI) has produced a total of 20 high-power laser systems that could be used to destroy any approaching enemy missiles or aircraft. The 20 units have been produced, funded in part as private research within the research and development arm of LTI, but the bulk of the funding came from a contract with the U.S. Department of Defense (DoD). Testing of the laser units has shown that they are effective defense weapons, and if redesigned to add portability and easier field maintenance, the units could be truck-mounted. The DoD has asked LTI to submit a bid for 100 units. The 20 units that LTI has built so far cost the following amounts and are listed in the order in which they were produced: Use Exhibit 6.4 and Exhibit 6.5.

However, the owner is concerned about recent energy price increases (including the price of gasoline), which affect virtually every aspect of the restaurant operation, including the price of food items and materials, delivery costs, and its own utilities.
