Question
Marginal income. The demand equation is p = f (x) and the income function is given by R (x) = px = xf (x) ACME
Marginal income. The demand equation is p = f (x) and the income function is given by R (x) = px = xf (x)
ACME company management plans to commercialize Electro-Stat fans. The marketing department has determined the demand for the fans is:
p=?0.03x+800 (0x20000)
Where p denotes unit price in dollars, and x the quantity demanded.
A. Determine the income function R (x)
B. Determine the marginal revenue function R (x)
C. Calculate R '(3000) and interpret the result
Marginal profit. Using the information from the previous problem. If the Electro-Stat fan production department estimates that the total dollar cost of producing x systems in one year will be:
C(x)=200x+600000)
Profit function (profit) = P (x) = R (x) -C (x) = (Profit = Revenues-cost)
Remember that the revenue function (R (x) or revenues) you defined in the previous problem.
a. Determine the profit function (Profit) P (x)
b. Determine the marginal profit function P (x)
c. Calculate P (2000) and interpret result
