Answer:
Option A $29.46 is correct.
Step-by-step explanation:
Credit card's billing cycle = 31 days
To calculate the average daily balance we must add Carla's balance from each day in the billing cycle and divide by the number of days of the month.
( Total balance × days ) / number of days of the month
(2560 × 15) ÷31 = $1238.71
Her credit card's APR is 28% Therefore Carla charged
(1238.71 × 0.28 × 31) ÷ 365
10,752.0028 ÷ 365 = 29.4575 Rounded to $29.46
Carla charged in interest for the billing cycle is $29.46.
