The credit card statement below details the transactions completed by Veronica on her credit card over the month of November.

\begin{tabular}{|r|r|}
\hline \multicolumn{1}{|c|}{ Transaction Description } & Transaction Amount \\
\hline Previous Balance: [tex]$\$[/tex] 4,224.00[tex]$ & \\
\hline November 1 Billing Date & \\
\hline November 7 Payment & $[/tex]\[tex]$ 100.00$[/tex] credit \\
\hline November 13 Charge: Sporting Goods & [tex]$\$[/tex] 74.00[tex]$ \\
\hline November 28 Charge: Online Retailer & $[/tex]\[tex]$ 77.00$[/tex] \\
\hline November 29 Charge: Shoe Store & [tex]$\$[/tex] 199.00[tex]$ \\
\hline November 30: End of billing cycle & \\
\hline Payment Due Date: December 8 & \\

\end{tabular}

Suppose the monthly interest rate on Veronica's credit card is $[/tex]3.93\%[tex]$ and the credit card company uses the average daily balance method to calculate interest.

1. Determine the average daily balance for the November billing cycle. Round the solution to the nearest cent, if necessary.

The average daily balance for November is $[/tex]\[tex]$ \square$[/tex]

2. Determine the interest to be paid on December 1, the next billing date. Round the solution to the nearest cent, if necessary.

The interest required to be paid on December 1 is [tex]$\$[/tex][tex]$ $[/tex]\square[tex]$

3. Determine the total balance due on December 1. Round the solution to the nearest cent, if necessary.

The total amount due on December 1 is $[/tex]\[tex]$ $\square$

4. The credit card company requires a minimum payment of $\$20$ if the balance at the end of the billing cycle is less than $\$225$. In the event that the balance due at the end of the billing cycle is greater than $\$225$, the minimum monthly payment is equal to $\frac{1}{20}$ of the balance due at the end of the billing cycle, rounded up to the nearest whole dollar. Determine the minimum monthly payment owed by Veronica that is due by December 8.

The minimum monthly payment is $\$[/tex] [tex]$\square$[/tex]



Answer :

Alright, let's go through the steps to determine the requested values based on Veronica's credit card statement for November.

Step 1: Calculate the Average Daily Balance

To determine the average daily balance, we need to account for the balance changes occurring throughout the billing cycle. Here’s how the balance changes over the month based on the transactions:

- November 1 to November 6:
* Balance = previous balance = \[tex]$4,224.00 * Number of days = 6 - November 7 to November 12: Balance for these days = \$[/tex]4,224.00 - \[tex]$100.00 = \$[/tex]4,124.00
Number of days = 6

- November 13 to November 27:
* Balance for these days = \[tex]$4,124.00 + \$[/tex]74.00 = \[tex]$4,198.00 * Number of days = 15 - November 28: Balance for this day = \$[/tex]4,198.00 + \[tex]$77.00 = \$[/tex]4,275.00
Number of days = 1

- November 29 and November 30:
* Balance for these days = \[tex]$4,275.00 + \$[/tex]199.00 = \[tex]$4,474.00 * Number of days = 2 Now, we add up the daily balances for each period: - Total from November 1-6: \(6 \times 4224.00 = 25344.00\) - Total from November 7-12: \(6 \times 4124.00 = 24744.00\) - Total from November 13-27: \(15 \times 4198.00 = 62970.00\) - Total from November 28: \(1 \times 4275.00 = 4275.00\) - Total from November 29-30: \(2 \times 4474.00 = 8948.00\) Sum of daily balances for the billing cycle: \[ 25344.00 + 24744.00 + 62970.00 + 4275.00 + 8948.00 = 126281.00 \] To find the average daily balance: \[ \text{Average daily balance} = \frac{126281.00}{30} = 4209.37 \] Therefore, the average daily balance for November is \( S = 4209.37 \). Step 2: Calculate the Interest to Be Paid Next, we use the average daily balance to calculate the interest. The annual interest rate is \(3.93\%\). \[ \text{Monthly interest rate} = \frac{3.93\%}{12} = 0.3275\% \] The interest to be paid is: \[ \text{Interest to be paid} = 4209.37 \times 0.003275 = 13.79 \] Therefore, the interest required to be paid on December 1 is \( \$[/tex] 13.79 \).

Step 3: Calculate the Total Balance Due on December 1

To find the total balance due, we need to add the interest to the previous balance adjusted for payments and new transactions:

[tex]\[ \text{Total balance due} = \$4224.00 - \$100.00 + \$74.00 + \$77.00 + \$199.00 + \$13.79 = 4487.79 \][/tex]

Therefore, the total amount due on December 1 is [tex]\( \$ 4487.79 \)[/tex].

Step 4: Calculate the Minimum Monthly Payment

Finally, to determine the minimum monthly payment:
- If the total balance due is less than [tex]\( \$225 \)[/tex], the minimum payment is [tex]\( \$20 \)[/tex].
- If the total balance due is greater than or equal to [tex]\( \$225 \)[/tex], the minimum payment is [tex]\( \lceil \frac{\text{total balance due}}{20} \rceil \)[/tex].

Here,
[tex]\[ \frac{4487.79}{20} = 224.39 \][/tex]

Rounding up to the nearest whole number:
[tex]\[ \text{Minimum monthly payment} = 225 \][/tex]

Therefore, the minimum monthly payment due by December 8 is [tex]\( \$ 225 \)[/tex].
