Bobby's Bottle Service Co. ("BBS") takes out a revolving line of credit to purchase inventory for its new bar and nightclub. American Bank gives BBS a $100,000 line of credit, with a 7% interest rate, and a maturity date of Jan. 1, 2025. BBS draws $20,000 from the line of credit to stock its bar for opening night. Opening night is a hit, and BBS then needs to draw another $20,000 to re-stock its bar. Five months later, BBS pays American Bank $15,000 toward its line of credit. At this time (and ignoring any interest that has accrued), what is the maximum amount BBS could draw from its line of credit with American Bank?
