need the answer.... PLZ will name the fist one to answer the brainliest!!!!!

Answer:
A. $3,992.50
Step-by-step explanation:
Pavi has a credit limit of $8,000.
The credit statement says that the current balance is $4,007.50.
The margin Pavi has is the limit ($8,000) minus the current balance ($4.007.50), so 8000 - 4007.50 = 3992.50
It could have been guessed easily, because the balance is roughly half of the credit limit... so what's left is roughly half of the credit limit. And the first answer is the only one close to that half-limit number ($4,000).
