Blossom Industries incurs unit costs of $$7($ $$4$ variable and $$3$ fixed$)$ in making an assembly part for its finished product. A supplier offers to make $10,900$ of the assembly part at $$5$ per unit. If the offer is accepted, Blossom will save all variable costs but no fixed costs. Prepare an analysis showing the total cost saving, if any, that Blossom will realize by buying the part. $($Enter negative amounts using either a negative sign preceding the number e$.$g$.-45$ or parentheses e$.$g$.(45).)$

The decision should be to the part.
