Answer:
0 means Katie has neither balance nor any debt
Step-by-step explanation:
Katie owes Mathews $10 meaning she has a debt (represented by a negative number). Katie also owes $5 to kabrina meaning she has a debt (represented by a negative number).
Katie has $3 in her pocket, meaning that she has a balance (represented by a positive number)
Therefore, if Katie has $0, this means she neither has any debt nor any balance.
