Answer:
In seven months
Step-by-step explanation:
Your credit score will begin to increase once you lower your balance to approximately 30% of the available credit. That means that you should try to lower your balance to only $600, assuming you stop using it.
If you are paying $150 per month, with a 12.5% APR, then it will take you seven months before your balance is approximately $600 ($604 to be exact).
