Revenue A small business assumes that the demand function for one of its new products can be modeled by p = Cekx. When p = $50, x = 900 units, and when p = $40, x = 1200 units. (a) Solve for C and k. (Round C to four decimalplaces and k to seven decimal places.) C = K = (b) Find the values of x and p that will maximize the revenue for this product. (Round x to the nearest integer and p to two decimal places.) X = units = $
