Final answer:
The finance charge on Michelle's credit card using a 1.6% interest rate would be $23.36, and her new balance on May 8 after accounting for the finance charge, additional charges, and payment would be $1154.72.
Step-by-step explanation:
Calculating the Finance Charge and New Balance on a Credit Card
To calculate the finance charge using the previous balance method with an interest rate of 1.6% per month on Michelle's credit card, you would use the formula:
Finance Charge = Previous Balance × Monthly Interest Rate
For Michelle, this would be:
Finance Charge = $1459.73 × 0.016
Therefore, the finance charge would be:
Finance Charge = $23.36
To find the new balance on May 8, you would add the finance charge to the previous balance, then subtract any payments made and add any new charges:
New Balance = (Previous Balance + Finance Charge + New Charges) - Payments
New Balance = ($1459.73 + $23.36 + $371.63) - $700
So, the new balance would be:
New Balance = $1154.72
