How would I explain:

1. my methodology?, and

2. my interpretation?

In an Evaluating Marketing Performance report.

My answers for each need to be relative lengthy and I am not sure how to answer these.

I have had to use a series of formulas to get answers based on a case study. The idea is to analyse if a company can extract more profit from current customers by either increasing the service fee or to change the service fee. We are also tasked with conducting a sensitivity analysis and make recommendations based on our findings. This needs to be achieved without incorporating the question itself in y answer.
