A prospective homeowner wants to determine how much she can borrow in the form of a fixed-rate 20-year mortgage. Mortgages of that maturity carry a fixed interest rate of 9.00%. She estimates that she can afford annual, pre-tax payments (interest plus principal) on her mortgage of $25,000 (for simplicity, assume that mortgage payments are made once a year at the end of the year).

Anew firm is developing its business plan. it will require $615,000 of assets, and it projects $450,000 of sales and $355,000 of operating costs for the first year. management is reasonably sure of these numbers because of contracts with its customers and suppliers. it can borrow at a rate of 7.5%, but the bank requires it to have a tie of at least 4.0, and if the tie falls below this level the bank will call in the loan and the firm will go bankrupt. what is the maximum debt ratio the firm can use? (hint: find the maximum dollars of interest, then the debt that produces that interest, and then the related debt ratio.)a. 41.94%b. 44.15%c. 46.47%d. 48.92%e. 51.49%
