Each unit of a product can be made on either machine A or machine B. The nature of the machines makes their cost functions differ. Machine A Machine B: C(x) = 10+ C(y) = 220 + Total cost is given by C(x,y) = C(x) + C(y). How many units should be made on each machine in order to minimize total costs if x + y = 25,760 units are required? units are produced on machine A and The minimum total cost is achieved when (Simplify your answer.) units are produced on machine B
