Problem
To increase its market share, Sole Brother Inc. decided to borrow $50,000 from its banker for the purchase of newspaper advertising for its shoe retail line. The loan is to be paid in four equal annual payments with 15% interest. The loan is discounted 12 points. The first 6 "points" are an additional interest charge of 6% of the loan, deducted immediately. This additional interest 6%(50, 000) = $3000 means the actual amount received from the $50,000 loan is $47,000. Another 6 points or $3000 of additional interest is deducted as four $750 additional annualinterest payments. What is the after-tax interest rate on this loan?
