Chapter 8 Homework Questions: 8-27, 8-29, 8-31, 8-35 8-27 Estimating Costs in an Uncertain EnvironmentMany companies face increasingly unpredictable costs and revenues as the recession affects demand for products and the costs of materials and labor for these products. Revenues and costs have fluctuated significantly in recent years for such cost elements as fuel, labor, commodities (agricultural commodities, metals, etc.), interest, and rent expense, among others. Dealing with the increased fluctuations requires cost estimation methods that are more sophisticated and more frequently updated. The result is that companies are including in their cost estimation additional independent variables. Moreover, these companies are updating their estimation models more frequently. For example, Southwest Airlines updates its revenue prediction model on a daily basis.RequiredConsider Southwest Airlines and the following six key areas of cost for the company.

Aircraft ownership costsANSWER: During a time of recession, the costs I believe the airlines must update frequently is the fuel cost. During a time of economic downfall, the price of fuel can fluctuate on a daily basis.Because of the frequent change in price, the airline’s expenses will continuously fluctuate as well, leaving the total expense of fuel at an indefinite amount. Ultimately, this negatively affects the airline company. 8-29 Cost ClassificationMatch each cost to the appropriate cost behavior pattern shown in graphs (a)through (l).
