A company makes and sells notebook computers. The company’s cost function in thousands of dollars is C(x) = 0.3x + 100, and the revenue function in thousands of dollars is R(x) = 0.75x, where x is the number of notebook computers.

(a) Evaluate and interpret C(100).

(b) Interpret the y-intercepts on the graphs of C and R.*

(c) Give the profit function P(x). P(x) = 0.45x - 100.

(d) How many computers need to be sold to make a profit?
