Answer:
Weight of debt, Wd = 0.4842 or 48.42%
Explanation:
WACC = Wd×Rd×(1-t)+We×Ke+Wp×Kp
W is weights of respective portfolios
R is return on respective portfolios
Wd+We+Wp = 1
9.50% = Wd×4.80%+(0.93-Wd)×14.70%+0.07×8.90%
9.5% = Wd×4.80%+13.671%-14.70%×Wd+0.623%
9.90%×Wd = 4.794%
Weight of debt, Wd = 0.4842 or 48.42%
