A company manufactures downhill skis. It has fixed costs of $26,000 and a marginal cost given by C'(x)=1+0.05x where C(x) is the total cost at an output of x pairs of skis. Use a table of integrals to find the cost function C(x) and determine the production level (to the nearest unit) that produces a cost of $150,000. What is the cost (to the nearest dollar) for a production level of 850 pairs of skis? Click the icon to view a brief table of integrals. C(x)= (Simplify your answer. Use integers or fractions for any numbers in the expression)
