Answer:
Balance transfer fee = $90
Explanation:
We are told that you transfer $3000 from another credit card.
For credit card holders, a balance transfer fee is basically a one-time fee you will have to pay when you transfer a balance from one credit card to another one.
Now, a balance transfer fee is usually deducted at 3% of the total amount transferred. That's the standard practice.
Thus, balance transfer fee = 3% × 3000 = $90
