cost of a commodity the price p, in dollars, of a certain commodity and the quanity x sold obey the demand equation p = -1/5x + 200 0 <= x < =1000. suppose that the cost c, in dollars, of producing x units is c = the square root of x/10 + 400. Assuming that all items produced are sold, find the cost c as a function of the price p, in dollars, of a certain commodity and the quantity x sold obey the demand equation
