Also calculate when the marginal cost appears to be lowest in which interval

The cost of recycling q tons of paper is given in the following table. q (tons) 1000 1600 2200 2800 3400 4000 C(q) 2400 3300 3650 3830 3900 4200 (dollars) Estimate the marginal cost at q = 2800. Interpret your answer in terms of cost. Round your answers to the nearest cent. C' (2800) ~ i This means that recycling the 2801st ton of paper will cost around $
