The price-demand equation and cost function for the production of high-end at irons are given as follows: pix} = 150 - 0.005x and (Six) = 100,000 + 10x where x is the number of at irons that can be sold at 5p per at iron and CM is the total cost (in dollars) of producing x at irons. {12 points) 1. Find the prot function. 2. Find the equation for the marginal prot. 3. Find the marginal prot when x = 500 and interpret this quantity
