The Toys-R-4-U Company has developed two new toys for possible inclusion in its productline for the upcoming Christmas season. Setting up the production facilities to beginproduction would cost $50,000 for toy 1 and $80,000 for toy 2. Once these costs arecovered, the toys would generate a unit profit of $10 for toy 1 and $15 for toy 2. Thecompany has two factories that are capable of producing these toys. However, to avoiddoubling the start-up costs, just one factory would be used, where the choice would bebased on maximizing profit. For administrative reasons, the same factory would be usedfor both new toys if both are produced. Toy 1 can be produced at the rate of 50 per hourin factory 1 and 40 per hour in factory 2. Toy 2 can be produced at the rate of 40 perhour in factory 1 and 25 per hour in factory 2. Factories 1 and 2, respectively, have500 hours and 700 hours of production time available before Christmas that could beused to produce these toys. It is not known whether these…

A supermall with two levels is under construction. The plan is to install only 9 elevators at the start, although the ultimate design calls for 16. The question arises as to whether to provide necessary facilities (supports, wiring conduits, motor foundations, etc.) that would permit the installation of the additional elevators at the mere cost of their purchase and installation or to defer investment in these facilities until the elevators actually need to be installed. Additional annual expenses are estimated at $7,000 for each elevator after it's installed. Assume these costs begin one year after the installation. At an interest rate of 12%, compare the net present worth of each option over eight years. The two options are: Option A Provide these facilities now for all seven future elevators at $300,000 Option B Defer the investment as needed. Install two more elevators in two years, three more in five years, and the last two in eight years. The installation of these facilities at…
