Assuming that the marginal cost function in given Problem is linear, find its equation and write a definite integral that represents the increase in costs going from a production level of 200 to 600 pairs of skis per week Evaluate the definite integral.
Problem
Cost. A company manufactures downhill skis. The research department produced the marginal cost graph shown in the accompanying figure, where C'(x) is in dollars and x is the number of pairs of skis produced per week. Estimate the increase in cost going from a production level of 200 to 600 pairs of skis per week. Use left and right sums over two equal subintervals. Replace the question marks with the values of L2 and R2 as appropriate:
