Please help, thanks.

Your uncle Fred just purchased a new boat. He brags to you about the low 6.9% interest rate (APR, monthly compounding) he obtained from the dealer. The rate is even lower than the rate he could have obtained on his home equity loan (8.1% APR, monthly compounding). But if his tax rate is 26% and the interest on the home equity loan is tax deductible, which loan is truly cheaper? The after-tax cost on the home equity loan is %. (Round to two decimal places.) Which is the cheaper loan? (Select the best choice below.) A. Both loans are the same when we account for taxes. B. The home equity loan is cheaper than the boat loan from the dealer when compared on an after-tax basis. O c. We cannot tell which loan is cheaper since we do not know the value of the principal amounts. OD. The boat loan from the dealer is cheaper than the home equity loan when compared on an after-tax basis
