The Boyles Ceramics, Inc. established a line of credit with a local bank. The maximum amount that can be borrowed under the terms of the agreement is $1,000,000 at an annual rate of 8 percent. A compensating balance averaging 25 percent of the amount borrowed is required. Prior to the agreement, Boyles had no deposit with the bank. Shortly after signing the agreement, Boyles needed $240,000 to pay off a note that was due. Boyles decides to borrow an amount sufficient to pay the $240,000 note and also to cover the compensating balance. What is the effective annual cost of credit if the loan is made on a discount basis?
