Answer:
She can spend a maximum of $2763.
Step-by-step explanation:
The credit card works as there can be a negative balance in the card. For example if Sally has a shortage of money and she is in need of some, she can take money from her credit card and then repay it later.
Here Sally already has $763 in her hand and her credit card can have a balance of maximum $2000.
So Sally can spend $763 which she already has in her hand and then spend a maximum of $2000 using her credit card.
So she can spend a maximum of $2673
