Zorn Corporation is deciding whether to pursue a restricted or relaxed working capital investment policy. The firm's annual sales are expected to total $$5,750,000,$ its fixed assets turnover ratio equals $4\mathrm{.}0,$ and its debt and common equity are each $50\%$ of total assets. EBIT is $$150,000,$ the interest rate on the firm's debt is $8\%,$ and the tax rate is $40\%.$ If the company follows a restricted policy, its total assets turnover will be $2\mathrm{.}5.$ Under a relaxed policy its total assets turnover will be $2\mathrm{.}3.$ If the firm adopts a restricted policy, how much lower would its interest expense be than under the relaxed policy? Do not round intermediate calculations.a$.$ $$9,600$ b$.$ $$8,000$ c$.$ $$16,000$ d$.$ $$4,800$ e$.$ $$4,000$
