Answer:
A) NPV= - $428,888.89 B) Company would break Even if g = 5.68%
Explanation:
Hi, we have to bring to present value all the inflows and outflows of cash, this is the formula to use and the math of it.


The question says that "at what constant growth rate would the company just break even..." and well, a NPV=0 is not precisely break even, actually, it means that the company is obtaining exactly what is asking for any investment, but let´s assume that the question was, what should the growth rate be for the company to accept this project?. So we have to solve the first equation for "g", that is:

So the constant growth rate has to be at least 5.68% for the company to accept this project (NPV=0)
Best of luck
