A company that produces ribbon has found that the marginal cost of producing x yards of fancy ribbon is given by C'(x) = 0.00002x2 0.04x + 48 for x s 800, where C'(x) is in cents. Approximate the total cost of manufacturing 800 yards of ribbon, using 5 subinteryals over [0,800] and the left endpoint of each subinteryal. The total cost of manufacturing 800 yards of ribbon is approximately 33 . (Do not round until the nal answer. Then round to the nearest cent as needed.)
