Answer:
Investors expect a return of 37.80 %.
Step-by-step explanation:
The return that investors expect is the cost of equity to Ricci Co.
Cost of Equity = Return on Risk Free Security + Beta × Risk Premium
Where,
Risk Premium = Return on Market Portfolio - Return on Risk Free Security
= 18.00% - 9.00%
= 9.00 %
Cost of Equity = 9.00% + 3.2 × 9.00 %
= 37.80 %
