The D.J. Masson Corporation needs to raise $500,000 for 1 year to supply working capital to a new store. Masson buys from its suppliers on terms of 3/10, net 90, and it currently pays on the 10th day and takes discounts. However, it could forgo the discounts, pay on the 90th day, and thereby obtain the needed $500,000 in the form of costly trade credit. What is the effective annual interest rate of this trade credit? PLEASE NOTE: I know the answer is 14.91%. This is what is stated in the textbook. My problem is coming to that answer. Please explain. First person with a good description will be rated 5 stars for full points.
