The demand equation for a certain product is given by p = 114 0.04z, where p is the unit price (in dollars) of the product and z is the number of units produced. The total revenue obtained by producing and selling units is given by R = 2p. Determine prices p that would yield a revenue of 8330 dollars. Lowest such price = Highest such price dollars (give answer to the nearest penny) dollars (give answer to the nearest penny)
