Current Designs faces a number of important decisions that require incremental analysis. Current Designs is always working to lidentify ways to increase efficiency while becoming more environmentally conscious. During a recent brainstorming session, one employee suggested to Diane Buswell, controller, that the company should consider replacing the ourrent rotomold oven as a way to realize savings from reduced energy consumption. The oven operates on natural gas, using 21.100. therms of natural gas for an entire year. A new, energy-efficient rotomold oven would operate on 18,600 therms of natural gas for an entire year. After seeking out price quotes from a few suppliers. Diane determined that it would cost appraximately $310,000 to purchase a new, energy-efficient rotomold oven She determines that the expected useful life of the new oven would be 10 years, and it would have no salvage value at the end of its useful life. Current Designs would be able to sell the current oven for $12,400. (a) Prepare an incremental analysis to determine if Current Designs should porchase the new rotomold oven, assuming that the average price for natural gas over the next 10 years will be 50.55 per therm.
