Final answer:
Bella has a change of $10 in the amount of money she has.
Step-by-step explanation:
To determine the change in the amount of money Bella has, we need to calculate the total amount she paid to the game store, subtract the return amount, and then subtract the initial payment amount.
- Bella paid 6 payments of $5 each, so the total amount she paid is 6 * $5 = $30.
- She received $20 back when she returned the game.
- Therefore, the change in the amount of money she has is $30 - $20 = $10.
