Ivanhoe Industries incurs unit costs of $8 ( $5 variable and $3 fixed) in making an assembly part for its finished product. A supplier offers to make 10,400 of the assembly part at $6 per unit. If the offer is accepted, Ivanhoe will save all variable costs but no fixed costs. Prepare an analysis showing the total cost saving, if any, that Ivanhoe will realize by buying the part. (Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).) uic rai
