DRAW ALL CASH FLOW DIAGRAMS - I do want the actual IRRs (no shortcut method unless absolutely necessary) 1. On January 1# 2015, Joe bought 100 stocks of Inox Metal Inc. for $55.0 each. This stock paid an average annual dividend of $2.50/stock at the end of each year until Joe sold all the stocks in December 31" of 2021 for $65.50 each. What is the IRR of this investment? Was it a good investment, given MARR of 8% per year? 2. An engineering company plans to start doing material testing in-house. Their new lab will cost$500k and will generate savings of $100k per year over a period of 10 years. What is the IRR for this investment and does it make sense of the MARR of this company is 12% per year
