A cable television company estimates that with x thousand subscribers its monthly revenue and cost (in thousands of dollars) are R(x) = 32x - .21x2 C(x) = 195 + 12x. Determine the company’s breakeven points; that is, find the number of subscribers at which profit equals zero, that is, the revenue equals the cost.
