Manufacturing
a manufacturer's total cost is c(q) = 0.1q ^ 3 - 0.5q ^ 2 + 500q + 200 dollars when q thousand units are produced . currently , 4,000 units (q = 4) are being produced and the manufacturer is planning to increase the level of production to 4,100 . use marginal analysis to estimate how this change will affect total cost .

Yes, that is the correct formula. to solve this problem given the number of years, plug in the number of years for t and plug the whole thing into the
