Assume that C(x) is in dollars and X is the number of units produced and sold. For the total-cost function C(x) = 0.01x² +0 4x + 20, find AC and C'(x) when x = 90 and AX-1
AC-
(Simplify your answer. Type an integer or decimal rounded to two decimal places as noeded)
C'(x) when X-90 is $ per unit.
(Type an integer or a decimal.)
