You would solve c) in nearly the same method you used to solve b). Always always always, maximize provits by setting marginal cost (MC) = marginal revenue (MR). MR is the first derivitive of total revenue. Since you got b) right, you probably correctly calculated MR = 715 - .2x. (Then you maximized by setting this equal to zero and solving for x -- correct??)
For c) set MR = MC. MC is the first derivitive of the Total cost function, so MC is simply 180.
Take it from here.
