Trina has a credit card that uses the adjusted balance method. For the first 10
days of one of her 30-day billing cycles, her balance was $780. She then
made a purchase for $170, so her balance jumped to $950, and it remained
that amount for the next 10 days. Trina then made a payment of $210, so her
balance for the last 10 days of the billing cycle was $740. If her credit card's
APR is 17%, which of these expressions could be used to calculate the
amount Trina was charged in interest for the billing cycle?

Answer:

We can say option A is the answer.

Step-by-step explanation:

Trina has a credit card that uses the adjusted balance method. For the first 10 days of one of her 30-day billing cycles, her balance was $780.

Trina then made a payment of $210.

We will subtract 210 from balance 780= [tex]780-210=570[/tex]

APR is = 17% so daily rate is = [tex]17/100/365[/tex] or [tex]0.17/365[/tex]

Hence, we can say option A is the answer.
