Answer: 26.85%
Step-by-step explanation:
Based on the information given in the question, the firm's cost of internal equity will be calculated as:
Cost of equity = (D1/Current price) + Growth rate
= (4.90 / 26.00) + 8.0%
=(4.9/26) + 0.08
=26.85%
Therefore, the firm's cost of internal equity is 26.85%.
