(Cost of short-term financing) The R. Morin Construction Company needs to borrow $90,000 to help finance the cost of a new $126,000 hydraulic crane used in the firm's commercial construction business. The crane will pay for itself in 1 year, and the firm is considering the following alternatives for financing its purchase: Alternative AThe firm's bank has agreed to lend the $90,000 at a rate of 12 percent. Interest would be discounted, and a 15 percent compensating balance would be required. However, the compensating-balance requirement would not be binding on R. Morin because the firm normally maintains a minimum demand deposit (checking account) balance of $22,500 in the bank. Alternative BThe equipment dealer has agreed to finance the equipment with a 1-year loan. The $90,000 loan would require payment of principal and interest totaling $104,967. a. Which alternative should R. Morin select? b. If the bank's compensating-balance requirement were to necessitate idle demand deposits equal to 15 percent of the loan, what effect would this have on the cost of the bank loan alternative? a. Which alternative should R. Morin select? The cost of alternative A would be %. (Round to two decimal places.)
