The relationship that is not functional is **Situation 3: the total amount of money charged monthly on credit cards to the number of credit cards owned**.
This is because one number of credit cards can correspond to multiple total amounts charged, depending on the spending habits associated with each card. For example, if a person has two credit cards, they could charge $500 on one and $200 on the other one month, amounting to $700 in total, or they could charge $300 on one and $100 on the other, amounting to $400 in total. Thus, the relationship does not provide a unique output (total amount charged) for each input (number of credit cards owned).
