Well done Carol!
You have only failed two answers:
A debt is an obligation owed by one party (the debtor) to a second party, the creditor; usually this refers to assets granted by the creditor to the debtor, but the term can also be used metaphorically to cover moral obligations and other interactions not based on economic value.
waste of money - money spent for inadequate return; "the senator said that the project was a waste of money"
waste, wastefulness, dissipation - useless or profitless activity; using or expending or consuming thoughtlessly or carelessly; "if the effort brings no compensating gain it is a waste"; "mindless dissipation of natural resources"
