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:
