Freida’s credit card has an APR of 13.73%, and it calculates her finance charge by using the daily balance method and a 30-day billing cycle. On September 1st, Freida had a balance of $449.22. During the month of September, she made a payment of $85.33 and a purchase of $60.99. How much greater will her September finance charge be if the purchase occurred on September 7th and the payment occurred on September 20th than it would be if the payment occurred on September 7th and the purchase occurred on September 20th?
From September 7 through September 19, the first timing has a balance $146.32 higher than the second: it includes the $60.99 purchase but not the $85.33 payment. The difference in finance charges is $146.32 × 13.73% × 13 ÷ 365, or about $0.72. Therefore, the answer is choice C, $0.72.
