###### Question details

- Given the following cost function, determine the level of
(nonzero) output at which the average cost function in minimized,
and the average cost at that level.

AC = 520 -160Q + 20Q^{2}

(10 points)

- An Average Cost is at a minimum when its derivative function (measuring its change) is zero.
