The cost function for producing x freestanding and y fireplace-insert stoves is C = 32xy + 150x + 245y + 1050. (a) Find the marginal costs (ac/ax and aclay) when x = 80 and y = 20. C(80,20) = Cy(80,20) = (b) When additional production is required, which model of stove results in the cost increasing at a higher rate? How can this be determined from the cost model? When additional production is required, the cost of the ---Select--- stove is increasing at a higher rate because aclay ? vacyx. Submit
