Answer:
Her total balance of credit card $151.50
Step-by-step explanation:
Michelle's credit card has a 1% introductory APR for 12 months. After that APR would be 19.9%.
Michelle makes purchases of $150.00 and she wants to pay off her balance before the grace period, so her total balance of the card is
( 1% of 150.00 ) + 150.00 = 01.50 + 150.00 = $151.50
She plans to pay off her total balance before the grace period ends,
Therefore she is eligible for only 1% APR
there would be No late fees, No annual membership, added to her balance.
