For a company that produces and sells x number of chairs per
month, the profit function is given by G (x) = -0.02x^2 + 200x -
40,000 and the marginal profit function by G' (x) = -0.04x + 200.
So, we can conclude that G' (8,900) =-156 can be interpreted as
follows:
a. The company has a loss of approximately $ 156 when 8,900
chairs are produced and sold.
b. The company has a loss of approximately $ 156 when 8,901
chairs are produced and sold.
c. The company has a loss of approximately $ 156 when chair #
8,901 is produced and sold.
d. Profit decreases approximately $ 156 when chair # 8,900 is
produced and sold.
e. Profit decreases approximately $ 156 when chair # 8,901 is
produced and sold.
