Using a modified discriminant function similar to Altman's, Burger Bank estimates the following coefficients for its portfolio of loans: Z $=1\mathrm{.}4$X$1+1\mathrm{.}09$X$2+1\mathrm{.}5$X$3$ where X$1=$ debt to asset ratio; X$2=$ net income, and X$3=$ dividend payout ratio. Using Z $=1\mathrm{.}682$ as the cut$-$off rate, what should be the debt to asset ratio of the firm in order for the bank to approve the loan? A$.40\mathrm{.}0$ percent. B$.46\mathrm{.}5$ percent. C$.51\mathrm{.}5$ percent. D$.54\mathrm{.}0$ percent. E$.65\mathrm{.}0$ percent.
