Vladimir has a credit card that uses the average daily balance method. For
the first 14 days of one of his billing cycles, his balance was $1050, and for
the last 17 days of the billing cycle, his balance was $1280. If his credit card's
APR is 19%, which of these expressions could be used to calculate the
amount Vladimir was charged in interest for the billing cycle?

You would then need to calculate the interests for that time period by dividing the annual interest rate by days in a year and multiply by total days in the billing cycle:

0.19/365 x 31

The finale Aquarian would be:

(0.19/365 x 31) ((1050 x 14) + (1280x17)) / ( 14+ 17)

The answer is B

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The expression for the given data will be calculated as below:-

Multiply 1050 by 14 and add to 1280 x 17 and divide by total days:

((1050 x 14) + (1280x17)) / ( 14+ 17)

To calculate the interests for that time period by dividing the annual interest rate by days in a year and multiplying by the total days in the billing cycle:

0.19/365 x 31

The final expression would be:

(0.19/365 x 31) ((1050 x 14) + (1280x17)) / ( 14+ 17)

Therefore, the correct expression is (0.19/365 x 31) ((1050 x 14) + (1280x17)) / ( 14+ 17). The correct option is B.
