Ouyang Inc. reports the following hypothetical data about its fleet miles and operating costs: Year Miles Operating Costs 2010 300,000 $120,000 2011 800,000 220,000 Use the high-low method to develop a cost-estimating equation for total annual operating costs. (Let X = annual fleet miles.)

A)Total annual costs=50,000+.8*X

B)Total annual costs=40,000+.8*X

C)Total annual costs=60,000+.8*X

D)Total annual costs=60,000+.4*X

E) Total annual costs=60,000+.2*X
