Question 4 • FowU - Financial Math - B
Using the adjusted balance method, subtract the payments from the $746.28 beginning balance and exclude the purchase: $746.28 − $140.00 − $28.76 = $577.52. The monthly rate is 17.02% ÷ 12, so the finance charge is about $8.19. For the daily balance method, the balances across the 30 days total $19,751.61, giving an average daily balance of $658.39; applying the daily rate, 17.02% ÷ 365, for 30 days gives about $9.21. The daily balance method is therefore about $1.02 greater, matching choice A.
