Answer:
weighted cost of capital for next year is 10.27 %.
Explanation:
Weighted cost of capital = Ke × (E/V) + Kd × (D/V)
Ke = Cost of Equity
  = Dividend Yield + Expected growth rate
  = $1.30 / $30.00 + 0.07
  = 0.11333 or 11.33 %
Kd = Cost of Debt
   = Interest × (1 - tax rate)
   = 11% × ( 1 - 0.21)
   = 8.69 %
Weighted cost of capital =  11.33 % × 60% + 8.69 % × 40%
                     = 10.27 %
