The financial statements provided below relate to W Corp. Assume that Ws tax rate is 40%, its WACC is 10%, and the prevailing risk-free rate is 3.0%. Based on this information, answer the questions below.

Based on the above, what is W's non-operating cash balance for 2017 (based on the use of average balances)? What is W's total net operating working capital for 2017 based on this analysis?

these are the answers but I need the work to see how to get the answers!

Avg Cash Balance = $386

Return Earned on Avg Cash Balance = 2.59% (86.33% of 3.0% risk free rate)

Non-Operating Cash Balance = $383.31 (makes $60.7 "wasting" cash a/k/a part of net operating working capital)

Net Working Operating Capital (NOWC) = $898.7
