Broyle Ltd.'s main supplier offers it credit terms of 1/10, n/30 on its purchases. Because cash flow is tight for Broyle, the company's CFO is trying to determine what the annual interest rate would be if the company passes up this discount and pays at the end of the 30-day credit period instead. Also, if Broyle can access a short-term loan with interest of 8%, which would provide it with the funds to take advantage of the purchase discount, should it do so?
