When she got home, on the 21st day, she checked her credit card bill on-line and it showed that she had been charged interest already even though her payment wasn’t past due. It turns out that interest is compounded daily on cash withdrawals, from the day the cash is withdrawn.
If the interest rate on cash withdrawals is 28%, what was her total bill when she got home?
