A generic WACC formula is shown below. There are multiple inputs to this formula. Assume you plan to use the WACC to discount an infinite series of cash flows. Which of the following answers describes a plausible way to solve for the cost of equity? Select all that apply.

WACC$=r_D(1-t)(\frac{D}{D+E})+r_E(\frac{E}{D+E})$

Use a CAPM with a long$-$term risk$-$free rate, a market risk premium around $10\%,$ and Walmart's equity beta.

Use a CAPM with a long$-$term risk$-$free rate, a market risk premium between $4-6\%,$ and Walmart's asset beta.

Use a CAPM with a long$-$term risk$-$free rate, a market risk premium between $4-6\%,$ and Walmart's equity beta.

Use the cost of equity at a competitor store $($like Target$)$ as your estimate of Walmart's cost of equity.

Use a constant growth model. Using a plausible perpetual growth rate $(g)$ and the current dividend $($D$0)$ you can solve for the next period's dividend payment $).$ Then using the current share price, g$,$ and D$1$ you can solve for the implied cost of equity.
