Shirley has a credit card that uses the previous balance method. The opening
balance of one of her 30-day billing cycles was $2830, but that was her
balance for only the first 2 days of the billing cycle, because she then paid off
her entire balance and didn't make any new purchases. If her credit card's
APR is 19%, which of these expressions could be used to calculate the
amount Shirley was charged in interest for the billing cycle?
O A. (1930)(2052830 20 $0)
OB. 5.30)(50)
O c. (09:16. 30)/20 $0 + 28 0 $2830
O D. (8 19.30 S2830)

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
