Average profit. Sparkle pottery has determined that the cost, in dollars, of producing x vases is given by C ( x ) = 4300 + 2.1 x 0.6 . If the revenue from the sale of x vases is given by R ( x ) = 65 x 0.9 , find the rate at which average profit per vase is changing when 50 vases have been made and sold.
