Bobloblaw Manufacturing is considering the purchase of an automated parts handler for the assembly and test area of its Pittsburgh, PA$,$ plant. The handler will cost $$250,000$ to purchase and another $$10,000$ to install. If the company undertakes the investment, it will automate part of the semiconductor and test area, reducing operating costs by $$70,000$ per year for the next ten years. Five years into the life of the project, however, Bobloblaw will have to spend an additional $$100,000$ to update and refurbish the handler. The handler will be depreciated straight$-$line to zero over $10$ years, and the additional investment $($refurbishing costs$)$ will also be depreciated straight$-$line to zero over the last $5$ years of the project. After $10$ years, the handler is expected to be worth $$5,000$ to a buyer of these used machines. Bobloblaw's tax rate is $30\%$ and its opportunity cost of capital is $12\%.$ Answer the following questions:

a$)$ Is this a good project for Bobloblaw? Explain your answer.

b$)$ Create a data table and graph showing how NPV changes with the discount rate $($sometimes called an NPV profile$).$ What can you tell about the project from this?
