Instructions Please use Excel to complete the "#8 Stock Valuation" Assignment. "A tech start-up company has just become public. It just paid $8 dividend per share, which will grow 20% for the next three dividends. Afterwards, the dividends will level off and grow at 4% per year forever. If the investors require 8% return on similar investments, what is the price of stock?" I would like you to implement this on Excel. Make your Excel spreadsheet as efficient as possible, including all the necessary inputs. After doing this on Excel, answer the following question by changing the inputs on Excel: Q1. What is the effect of increasing the required return on equity? Q2. What is the effect of increasing the first- stage dividend growth rate? Q3. What is the effect of increasing the second- stage growth rate
