Step-by-step explanation:
The function of money that is illustrated when Mia deposits money in her piggy bank is the store of value.
Money serves as a store of value when it can be saved and held for future use. By depositing money in her piggy bank, Mia is storing her money in a safe place where she can access it later. This allows her to save money and accumulate wealth over time.
For example, let's say Mia deposits $100 in her piggy bank. A year later, she can open her piggy bank and use the money to buy something she wants. In this case, her piggy bank acts as a store of value because it preserves the purchasing power of her money over time.
