Answer:
Cost of equity is 30.33%
Step-by-step explanation:
A required return on assets of 14% means that a company requires a minimum acceptable rate of return of 14% at any investment which must yield the said return for its investors or for the resources/assets invested therein. We may use this return as the Company's Weighted Average Cost of Capital (WACC).
WACC formula:
WACC = ((Weight of debt financing) * (after tax cost of debt)) + ((Weight of equity financing) * (cost of equity))
Substituting the values, we get "X" as the weighted cost of equity (assuming no taxes as stated in the problem):
14% = (70%*7%) + X
14% = 4.900% + X
X = 9.100%
To get the cost of equity, we substitute the values for the following formula of the weighted cost of equity to get "X" as the cost of equity:
Weighted cost of equity = Weight of equity financing * cost of equity
9.100% = 30% * X
X = 30.33%
Cost of equity is 30.33%
