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: Upper C (x )equals 50 plus StartFraction x squared Over 6 EndFraction Machine B: Upper C (y )equals 220 plus StartFraction y cubed Over 9 EndFraction Total cost is given by C(x, y)equalsUpper C (x )plus Upper C(y ). How many units should be made on each machine in order to minimize total costs if xplusyequals17 comma 030 units are required
