9. Use the revenue function from problem 8 and the given cost function: R(x) = x(2,000 60x) Revenue Function C(x) = 4,000 + 500x Cost Function where x is thousands of computers, and R(x) and C(x) are in thousands of dollars. Both functions have domain of I S x S 25. 3) Find the prot function. P(x) = b) If you complete the square on the profit function you would get P(x) = -60(x2 -25x + 156.25) + 13,3 75 Finish completing the square to write in Vertex Form and find the maximum Prot. P(x) = Maximum Profit: c) What is the wholesale price per computer (to the nearest dollar) that produces the maximum Prot? Recall the price-demand function is p = 2000 60x
