The price-demand equation and the cost function for the production of hand woven silk scarves are given, respectively, by
p=60 - 2√xand C(x) = 3,000 + 5x
where x is the number of scarves that can be sold at a price of $p per unit and C(x) is the total cost (in dollars) of producing x scarves.
(A) Express the revenue function in terms of x.
(B) Graph the cost function and the revenue function in the same viewing window for 0 ≤ x ≤ 900. Use approximation techniques to find the break-even points correct to the nearest unit.
