High-Low Cost Estimation Assume the local DHL delivery service hub has the following information available about fleet miles and operating costs:

Year Miles Operating Cost

2010 554,000 $179,000

2011 674,000 $215,000

Use the high-low method to develop a cost-estimating equation for total annual operating costs. (Let X = annual fleet miles.) Total annual costs = Answer 0 + Answer 0 * X
