Answer:
$49.
Step-by-step explanation:
We have been given that Adele got a new credit card with an APR of 20% a month ago, and she just got her first credit card statement. She charged a sweater for $29, a scarf for $12, and a pair of mittens for $8.
Let us find the amount shown on Adele first credit card statement.
Since this Adele's 1st credit card statement, so she has no previous balance.
We are told that her credit card charges interest on the previous monthly balance, therefore, Adele should pay $49 now so that she doesn't have any interest charged to her on next months statement.
