The total cost (in dollars) of producing x coffee machines is C(x) = 1800 + 60x – 0.6x². II (A) Find the exact cost of producing the 21st machine. Exact cost of 21st machine = (B) Use marginal cost to approximate the cost of producing the 21st machine. Approx. cost of 21st machine =

The cost to produce to produce q electric cat brushes is described by the function.  C(q)=10q^2+250q where q is hundreds of units for volumes less then 2000.  The demand function for electric cat brushes is described by the function p (q)=-q^2-3q+1280 where represents price in dollars. A What are the company's marginal cost and marginal revenue functions? B Calculate the number of units thaat produce maximum profit.  what prices should the company charge and what is the maximum profit it will earn. C Find the company's functions for average cost per unit and determine the average cost per unit at the profit maximizing level of production. Please answer all parts of the question

Consider the cost function C(x) = −x^3 + 10x^2 + 20x. Find the maximum of the average cost function.

A company's cost (in dollars) to produce x units is C(x) = 82 + 6x -0.04x^2. Find the marginal cost when 25 units are sold. Round to the nearest cent, and do not enter the dollars sign.
