Final answer:
Stephanie's credit card balance at the end of 12 months would be $11,735.26.
Step-by-step explanation:
To calculate the balance at the end of 12 months, we need to use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
- A is the final amount (balance)
- P is the initial amount (credit card balance)
- r is the annual interest rate (APR) in decimal form
- n is the number of times the interest is compounded per year (365 for daily compound interest)
- t is the number of years (1 in this case since it's 12 months)
Plugging in the given values, we have:
A = 11300 * (1 + (0.12/365))^(365*1) = $11,735.26
Therefore, Stephanie's balance at the end of 12 months would be $11,735.26.
