Answer:
Explanation:
The solution to this problem involves calculating the monthly interest and reducing the balance accordingly each month until the balance reaches zero. Here are the steps:
Calculate the monthly interest: First, we need to calculate the monthly interest rate. We can do this by dividing the APR by 12. The monthly interest rate is 9.5% / 12 = 0.7917%.
Calculate the interest charge for the first month: The interest charge for the first month is the balance multiplied by the monthly interest rate. In this case, the interest charge is $1,367.90 x 0.7917% = $10.87.
Calculate the new balance: Next, we need to subtract the payment from the balance and add the interest charge to determine the new balance. The new balance after the first payment is $1,367.90 - $400.00 + $10.87 = $978.87.
Repeat the steps for subsequent months: Repeat the process of calculating the monthly interest charge and the new balance for each subsequent month until the balance reaches zero.
Keep track of the number of months: As we repeat the steps, keep track of the number of months it takes to pay off the card.
Here is a summary of the calculations:
Month Balance Interest Payment New Balance
1 $1,367.90 $10.87 $400.00 $978.87
2 $978.87 $7.74 $400.00 $586.61
3 $586.61 $4.62 $400.00 $191.23
4 $191.23 $1.50 $400.00 $-208.27
It takes 4 months to pay off the card, and the total amount paid including interest is $1,367.90 + $10.87 + $7.74 + $4.62 + $1.50 = $1392.73.
