Question 2 (Make or Buy) Emil Manufacturing incurs unit costs of $7.50 ($4.50 variable and $3.00 fixed) in making a sub-assembly part for its finished product. A supplier offers to make 10,000 of the parts for $5 per unit. If it accepts the offer, Emil will save all variable costs and $1 of fixed costs. Prepare an analysis showing the total cost savings, if any, that Emil will realize by buying the part. [S marks]
