The owner of a photocopy store charges 8 cents per copy for the first 100 copies and 6 cents per copy for each copy exceeding 100. In addition, there is a setup fee of $2.90 for each photocopying job (a) Determine R(x), the revenue from doing one photocopying job consisting of x copies. (b) If it costs the store owner 4 cents per copy, what is the profit from doing one photocopying job consisting of x copies? (Recall that profit is revenue minus cost.) (a) Choose the correct answer below. O A. 08x + 2.90 1 = x = 100 O B. .08x + 2.90 1 sx = 100 R(X) = R(x) = 06x + 4.90 100
