Recall that to find the cost to produce the nth unit in a production process, we calculate the difference С(n) — С(п — 1) where C(n) is the cost of producing n units. The total cost (in dollars) of producing x coffee machines is C(x) = 2400 + 70x – 0.3x². - (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 =
