Answer:
<u>$23.33 </u>more for the previous balance method than for the adjusted balance method
Explanation:
First you need to find out how much the interest would be for each method, then subtract to find how much more is charged for the "previous balance method."
Previous balance method calculates interest on the 31 days from the last statement balance, regardless of whether or not you have made payments since. So, .28 * $3,300 * 31/365 = $78.48 (rounded) for <u>previous balance method</u>
Now, adjusted balance method charges interest on the actual balance and number of days.
For 15 days, balance was $3,300
For the remaining 16 days (31-15 =16), balance was $1,400 (3300-1900)
.28 * $3300 * 15/365 = $37.97
.28 * $1400 * 16/365 = $17.18
Add the 2 sections together: 37.97+17.18 = $55.15 <u>for adjusted balance method.</u>
Finally, find the difference between the two methods: $78.48- 55.15 = $23.33.
So the previous balance method costs you $23.33 more than the adjusted balance method.
