Use the revenue function from Problem 69 and the given cost function:

R(x) = x(75 - 3x)     Revenue function
C(x) = 125 + 16x     Cost function

where x is in millions of chips, and R(x) and C(x) are in millions of dollars. Both functions have domain 1 ≤ x ≤ 20.
(A) Sketch a graph of both functions in the same rectangular coordinate system.
(B) Find the break-even points to the nearest thousand chips.
(C) For what values of x will a loss occur? A profit?
