Suppose drug retailer CVS has an equity beta of 0.80 and a debt-equity ratio of 0.10. Estimate its asset beta assuming its debt beta is zero. Suppose CVS were to increase its leverage so that its debt-equity ratio was 0.50. Assuming its debt beta were still zero, what would you expect its equity beta to be after the increase in leverage?

Please explain all work, including the rationale behind variables and numbers chosen
