Final answer:
Jackson would pay $327 in interest on his credit card loan.
Step-by-step explanation:
To calculate the interest paid on a loan, we can use the formula: Interest = Principal x Rate x Time.
Given that Jackson borrowed $3,000 with an interest rate of 10.9% and a repayment period of 3 years, we can plug in the values into the formula:
Interest = $3,000 x 10.9% x 3 years = $327.
Therefore, the correct answer is C) $327.
