Math Problem Statement
Market research indicates that consumers will buy x thousand units of a particular
kind of coffee maker when the unit price is p(x) = 0.27x + 51 dollars. The cost of
producing the x thousand units is C(x) = 2.23x
2 + 3.5x + 85 thousand dollars.
a. What are the revenue and profit functions, R(x) and P(x), for this production
process?
b. For what values of x is production of the coffee makers profitable?
