A company must decide between scrapping or reworking units that do not pass inspection. The company has $16,000$ defective units

that cost $$5\mathrm{.}70$ per unit to manufacture. The units can be sold as is for $$3\mathrm{.}10$ each, or they can be reworked for $$4\mathrm{.}70$ each and then

sold for the full price of $$8\mathrm{.}80$ each. If the units are sold as is$,$ the company will be able to build $16,000$ replacement units at a cost of

$$5\mathrm{.}70$ each, and sell them at the full price of $$8\mathrm{.}80$ each.

What is the incremental income from selling the units as scrap and reworking and selling the units? Should the company sell the units

as scrap or rework them? $($Enter costs and losses as negative values.$)$
