Last year, Jandik Corp. had $250,000 of assets, $18,750 of net income, and a debt-to-total-assets ratio of 37%. Now, suppose the new CFO convinces the president to increase the debt ratio to 48%.

By how much would the change in the capital structure improve the ROE?
a) 2.09%
b) 2.19%
c) 2.14%
d) 2.52%
