Answer: Sell their personal assets
Explanation: In the given case, James and Maria were the owners of a firm which has a partnership structure and not the company structure. As per the law, the owners and the firm in a partnership structure would not be considered as two separate legal entities.
In case of any default or liquidation , the personal assets of the owners of the firm could be taken into consideration for repayments of debt.
Hence Maria and Jamie can sell their assets to repay $37,500.
