At year 0, Dividend per share is $ 2.87
At year 1, Dividend per share is Div prev year * 1.25 or 2.87 * 1.25 = 3.5875
At year 2, Dividend per share is 3.5875 * 1.25 = 4.4844
At year 3, Dividend per share is = 4.4844 * 1.25 = 5.6055
At year 4, Dividend per share is = 5.6055 * 1.25 = 7.0068
At year 5, Dividend per share is = 7.0068 * 1.25 = 8.7585
At year 6, Dividend per share is = 8.7585 * 1.06 = 9.2841
At year 7, Dividend per share is = 9.2841 * 1.06 = 9.8411
At year 8, Dividend per share is = 99.8411 * 1.06 = 10.4316
Or using the equation D8 = 2.87*(1.25)^5 * 1.06^3 = 10.4316
Answer is 10.4316
