Indigo Manufacturing incurs unit costs of $$8\mathrm{.}30($$$5\mathrm{.}30$ variable and $$3\mathrm{.}00$ fixed$)$ in making a sub$-$assembly part for its finished product. A supplier offers to make $18,300$ of the parts for $$5\mathrm{.}80$ per unit. If it accepts the offer, Indigo will save all variable costs and $$1\mathrm{.}00$ of fixed costs. Prepare an analysis showing the total cost savings, if any, that Indigo will realize by buying the part. $($Round per unit answers to $2$ decimal places, e$.$g$.15\mathrm{.}25.$ If an amount reduces the net income then enter with a negative sign preceding the number, e$.$g$.-15,000$ or parenthesis, e$.$g$.(15,000).)$
