A manufacturer incurs the following costs in producing x water ski vests in one day, for 0

A manufacturer incurs the following costs in producing x water ski vests in one day, for 0 <x< 175: fixed costs, $125 unit production cost, $10 per vest; equipment maintenance and repairs, 0.05x dollars. So, the cost of manufacturing x vests in one given day is given tby c(x-0.o5x2+10x 125, where o<x<175. (A What is the average cost C(x) per vest ifx vests are produced in one day? (B) Find the critical numbers of C(x), the intervalson which the average cost per vestis decreasing, the intervals on which the average cost per vest is increasing, and the local extrema.
