please help me quick...thanks so much

To find John's finance charge and the new balance at the beginning of the next month, we'll follow these steps:

Step 1: Calculate the finance charge.
The finance charge is the interest John has to pay on the unpaid balance. To calculate this, we need to find the unpaid balance at the beginning of the month, which is the initial debt minus the payment made:
Unpaid balance = Initial debt - Payment
= $1,177.79 - $430.00
= $747.79

Next, we calculate the finance charge by applying the interest rate to the unpaid balance:
Finance charge = Unpaid balance * Interest rate
= $747.79 * (4.5% / 100)
= $33.65

Therefore, John's finance charge is $33.65.

Step 2: Calculate the new balance at the beginning of the next month.
To find the new balance, we need to add the finance charge to the sum of the unpaid balance and the purchases made during the month:
New balance = Unpaid balance + Finance charge + Purchases
= $747.79 + $33.65 + $366.02
= $1,147.46

Therefore, the new balance at the beginning of the next month is $1,147.46.

In summary, John's finance charge is $33.65, and his new balance at the beginning of the next month is $1,147.46.
