Perot Corporation is developing a new CPU chip based on a new type of technology. Its new chip, the Patay $2$ chip, will take two years to develop. However, because other chip manufacturers will be able to copy the technology, it will have a market life of two years after it is introduced. Perot expects to be able to price the chip higher in the first year, and it anticipates a significant production cost reduction after the first year. The relevant information for developing and selling the Patay $2$ is given as follows:

b$.$ Perot's engineers have determined that spending $$10$ million more on development will allow them to add even more advanced features. Having a more advanced chip will allow them to price the chip $$50$ higher in both years $($ $$870$ for year $1$ and $$700$ for year $2).$ What is the NPV of the project if this option is implemented?
