Last year, a toy manufacturer introduced a new toy truck that was a huge success. The company invested $$7\mathrm{.}50$ million in a plastic injection molding machine $($which can be sold for $$7$ million immediately$)$ and $$300,000$ in plastic injection molds specifically for the toy $($not valuable to anyone else$).$ The cost of labor and materials necessary to make each truck runs about $$2.$ This year, a competitor has developed a similar toy, significantly reducing demand for the toy truck. Now, the original manufacturer is deciding whether it should continue production of the toy truck.
