Last year, Candle Corp had $$200$ of assets, $$300$ of sales, $$20$ of net inome, and a liability to asset ration of $40\%.$ The new CFO believes a new computer program will enable it to reduce costs and thus raise net income to $$30\mathrm{.}8.$ Assets, sales, and the liability to asset ratio would not be affected. By how much would the cost reduction improve the ROE?
