Yellowknife Mining has 90 million shares that are currently trading for $2 per share and $130 million worth of debt. The debt is risk free and has an interest rate of 6%, and the expected return of Yellowknife stock is 10%. Suppose a mining strike causes the price of Yellowknife stock to fall 30% to $1.40 per share. The value of the risk-free debt is unchanged. Assuming there are no taxes and the risk (unlevered beta) of Yellowknife's assets is unchanged, what happens to Yellowknife's equity cost of capital? Equity cost of capital is \%. (Round to two decimal places.)
