Lancaster Lumber buys $8 million of materials (net of discounts) on terms of 3/5, net 60, and it currently pays on the 5th day and takes discounts. Lancaster plans to expand, which will require additional financing. Assume 365 days in year for your calculations.

What would be the nominal cost of that credit? Do not round intermediate calculations. Round your answer to two decimal places. %

What would be the effective cost of that credit? Do not round intermediate calculations. Round your answer to two decimal places. %

If the company could get the funds from a bank at a rate of 7%, interest paid monthly, based on a 365-day year, what would be the effective cost of the bank loan? Do not round intermediate calculations. Round your answer to two decimal places. %

Should Lancaster use bank debt or additional trade credit?
