Ordering cost = Fixed cost = \$700

Purchase cost per unit = Variable Cost = \$12.25

Annual Cost of buy option = \$700 + (\$12.25)Q = 700 +(12.25)(25000)

Annual Cost of buy option = \$306,950

For Make option:

Machine cost = Fixed cost = \$25,000

Production Cost per unit = Variable Cost = \$9.00

Annual Cost of Make option = \$25,000 + (\$9)Q = 25,000 + (9)(25000)

Annual Cost of Make option = \$250,000

Since the annual cost of Make option is less than buy option, manager should make the parts if demand is estimated to be 25,000 units

ANS: B. Make the part
