Embry Riddle Aeronautical University PAN Airways Cash Flow Valuation Worksheet

 

This is a finance excel assignment that consists of 4 parts, and I only need part 4 completed. I am having difficulty figuring out how to get the interest rate as well as the rest of the data for the section. The interest rate is supposed to be provided in part 1 of the excel sheet but I am unsure as to which one it is.
