Answer: -0.55
Step-by-step explanation: We can assume we start off with 0$ of money, so if you lose 1 quarter, 2 dimes, and 2 nickels you would be 55 cents in debt, so 55 cents in debt would be -0.55. -25-20-10=-55.
Unless you are looking for the amount of money not counting whether or not you are in debt so that would just be 0.55.
