How would I go about calculating the impact of uncertain future inflation on NPV of a proposed ambulatory surgery center based on given levels of net patient revenue inflation and levels of cost inflation? Here's what I am given and have already calculated:

The follow boxes must be filled with NVPs:

What implications do these results have?
