同学,选择X(machine time)的最高与最低点。 y=a+bx y= maintenance cost a= fixed cost b=variable cost x= machine hours b=(850,000-450,000)/(5,000-1,800)= $125 850,000=a +125*5,000 a= 225,000 y= 225,000+125*machine time Capacity= 262,500*80%=210,000 Batch time= 210,000/1 ,000=210 Machine time =210*14=2,940 Maintenance cost= 225,000+ 125*2,940= $592,500
