Buchholz Corporation follows a moderate current asset investment policy, but it is now considering a change, perhaps to a restricted or maybe to a relaxed policy. The firm's annual sales are $400,000; its fixed assets are $100,000; its target capital structure calls for 50% debt and 50% equity; its EBIT is $35,000; the interest rate on its debt is 10%; and its tax rate is 25%. With a restricted policy, current assets will be 15% of sales, while under a relaxed policy they will be 25% of sales. What is the difference in the projected ROEs between the restricted and relaxed policies?

a. 5.91%

b. 6.56%

c. 7.22%

d. 7.94%
