suppose that the dollar cost of producing x washing machines is c(x)= 2000 + 100x-0.1x6^2
a) find the average cost of producing 100 washing machines.
b) find the marginal cost when 100 washing machines are produced.
c(x)= 2000 + 100x-0.1x6^2: the only equation given
The Attempt at a Solution
i've tried taking the derivative and then substituting it with 100. for part a and for part b i didnt take the derivative, just plugged in 100 into the equation given
