Answer:
1. Book value of equity
6 million x 8 = 48million
Book value of debt = 65 + 40 = 105 million
Total value = 105 + 48 = 153 million
Weight of equity = 48/153 = 0.3137
Weight of debt = 105/153 = 0.6863
2. Market value
= 6 million x 85 = 510million
= Market value of debt = (65m * 0.95) + (40m * 1.08)
= 61.75m + 43.2m
= 104.95million
Total value = 104.95 + 510 = 614.95million
Weight of equity on market value = 510/614.95 = 0.8293
Weight of debt on market value = 104.95/614.95 = 0.1707
3. Market value of weights are more relevant
