Oindexter has a credit card that uses the average daily balance method. for the first 15 days of a 31-day billing cycle, his balance was $2110, but then he paid off his entire balance and didn't make any new purchases. if his credit card's apr is 26%, how much was poindexter charged in interest for the billing cycle? hurry

The answer is option C: $22.55.

Step-by-step explanation:

Given is that Poindexter’s credit card uses the average daily balance method.

For the first 15 days of a 31-day cycle, his balance was $2110

He paid off his entire balance and didn't make any new purchases after that.

Means for the first 15 days, the balance was $2110 and for last 16 days the balance was$0.

The APR is 26% or 0.26

The interest can be calculated as:

≈ $22.55

The interest charged was $22.55

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
