Vladimir has decided to discontinue his Bachelor of Laws course at the University of Wollongong and start his own franchise business. After failing to get finance from the major lenders, he successfully obtained a loan of $$500,000$ from $$We$$ll Lend When Others Won$$t Ltd$.$ This loan is at an interest rate of $15\%$ per annum. Vladimir signed a very lengthy, complex and detailed loan contract.

Vladimir is as unsuccessful with his franchise business as he was with his university course and is unable to meet the loan repayments. When Vladimir contacted his lender to discuss his problems, he was referred to the punitive conditions in the loan agreement, which will see the lender financially support him, but only at an interest rate of $25\%$ per annum. Vladimir argues that this is contrary to their motto of $$Assisting the Small Business Owner when the Big Financiers Will Not$.$
