Final answer:
The effective annual rate is approximately 11.22%.
Step-by-step explanation:
To calculate the effective annual rate when the credit card charges a percentage compounded daily, we can use the formula:
Effective Annual Rate = (1 + (nominal rate / number of compounding periods per year))^number of compounding periods per year - 1
Given that the credit card charges 10.64 percent compounded daily, we have:
Nominal rate = 10.64%
Number of compounding periods per year = 365
Substituting these values into the formula, we get:
Effective Annual Rate = (1 + (10.64% / 365))^365 - 1
Calculating this equation gives us approximately 11.22%. Therefore, the effective annual rate is 11.22%.
