Hillary used her credit card to buy a $804 laptop, which she paid off by making identical monthly payments for two and a half years. Over the six years that she kept the laptop, it cost her an average of $0.27 of electricity per day. Hillary’s credit card has an APR of 11.27%, compounded monthly, and she made no other purchases with her credit card until she had paid off the laptop.

(Assume that there were two leap years over the period that Hillary kept the laptop, and round all dollar values to the nearest cent.)
