Answer:
D) make the new product and buy the part to save $15,000
Explanation:
Total Cost to Make a Product = Cost per unit * units = 14*5,000 =70,000
Relevant cost to Buy the Product
= Cost to purchase per Unit + Fixed Overhead Per Unit - Contribution Per Unit From New Product
= $14+2 -5 = 11.00 Per Unit
Cost to Buy = 11,,00*5000 =55,000
Net Advantage to Buy = 70,000-55000 = $15,000
