On 31 October 2013, Josh borrowed money from his parents. He promised that he would repay the money on 31 October 2017, with interest at a nominal interest rate of 7% p.a., compounding quarterly. The total amount that he was due to pay his parents at that time was exactly $10,000 but he started his studies at university so he couldnt afford to repay the loan. If interest continues to accrue, what amount must Josh pay on 31 October 2022 to fully pay off the loan?
