B. $234.00

To find the final price of the coat, we need to calculate the price after each markdown.

1. First markdown: 20% of $325 = 0.20 x $325 = $65
Price after first markdown = $325 - $65 = $260

2. Second markdown: 10% of $260 = 0.10 x $260 = $26
Price after second markdown = $260 - $26 = $234

Therefore, the Christmas shopper in December would pay $234 for the coat.

The coat's original price is $325.00. After a 20% discount in November, the price becomes 80% of $325:
\[ 325 \times 0.8 = 260 \, \text{dollars} \]

In December, an additional 10% discount is applied to the reduced price, so the final price is 90% of $260:
\[ 260 \times 0.9 = 234 \, \text{dollars} \]

Alternatively, combining the discounts:
\[ 325 \times 0.8 \times 0.9 = 325 \times 0.72 = 234 \]

The final price is **$234.00**, corresponding to option **B**.

GPT-4o To determine the final price of the coat, we need to apply the successive discounts step by step.

1. First, calculate the price after the 20 percent markdown in November:
- 20 percent of $325.00 is \( 0.20 \times 325 = 65 \).
- Subtracting this amount from the original price, the price becomes \( 325 - 65 = 260 \).

2. Next, calculate the price after the additional 10 percent markdown in December:
- 10 percent of $260.00 is \( 0.10 \times 260 = 26 \).
- Subtracting this amount from the November price, the final price becomes \( 260 - 26 = 234 \).

Thus, a Christmas shopper in December would pay $234.00 for the coat.

To solve this problem, first find 20 percent of $325.00, which is $65.00. Then subtract $65.00 from $325.00 to get $260.00. Next, find 10 percent of $260.00, which is $26.00. Finally, subtract $26.00 from $260.00 to get $234.00.

B. $234.00

To find the final price of the coat, we need to calculate the price after each markdown.

1. First markdown: 20% of $325 = 0.20 x $325 = $65. So, the price after the first markdown is $325 - $65 = $260.
2. Second markdown: 10% of $260 = 0.10 x $260 = $26. So, the price after the second markdown is $260 - $26 = $234.

Therefore, the Christmas shopper in December would pay $234 for the coat.

doubao The coat is initially marked down by 20%, so the price becomes 325 - (325 * 0.2) = 325 - 65 = 260. Then it is marked down an additional 10%, so the final price is 260 - (260 * 0.1) = 260 - 26 = 234. The answer is B. B
minimax First, calculate the price after the first markdown of 20 percent in November:

20% of $325.00 = 0.20 * $325.00 = $65.00

Subtract this discount from the original price to find the new price:

$325.00 - $65.00 = $260.00

Now, calculate the additional 10 percent markdown in December:

10% of $260.00 = 0.10 * $260.00 = $26.00

Subtract this discount from the price after the first markdown:

$260.00 - $26.00 = $234.00

So, the Christmas shopper in December would pay $234.00 for the coat.

The correct answer is B. $234.00.

kimi First, let's calculate the price after the first markdown in November:

Original price = $325.00
Discount in November = 20% of $325.00 = 0.20 * $325.00 = $65.00

Price after November markdown = Original price - Discount in November
Price after November markdown = $325.00 - $65.00 = $260.00

Next, let's calculate the price after the additional markdown in December:

Additional discount in December = 10% of $260.00 = 0.10 * $260.00 = $26.00

Price after December markdown = Price after November markdown - Additional discount in December
Price after December markdown = $260.00 - $26.00 = $234.00

Answer: B. $234.00
B
wenxinyiyan B. $234.00

Explanation:

1. The coat has a list price of $325.00.
2. In November, the merchant marked it down by 20%. To calculate the new price, we subtract 20% of the original price from the original price:
$325.00 - (0.20 \times $325.00) = $325.00 - $65.00 = $260.00$
So, after the November markdown, the coat's price is $260.00.
3. In December, the merchant marked it down by an additional 10%. To calculate the new price, we subtract 10% of the November price from the November price:
$260.00 - (0.10 \times $260.00) = $260.00 - $26.00 = $234.00$
So, after the December markdown, the coat's price is $234.00.

Therefore, a Christmas shopper in December would pay $234.00 for the coat.

zhipu First, calculate the price after the initial 20% markdown:

Original price = $325.00

Markdown = 20% of $325.00
= 0.20 × $325.00
= $65.00

Price after 20% markdown = $325.00 - $65.00
= $260.00

Next, calculate the price after the additional 10% markdown:

Markdown = 10% of $260.00
= 0.10 × $260.00
= $26.00

Price after additional 10% markdown = $260.00 - $26.00
= $234.00

Therefore, a Christmas shopper in December would pay $234.00 for the coat.

deepseekv3 To determine the final price of the coat after the two markdowns, follow these steps:

1. **First Markdown (November):**
- Original price: $325.00
- Markdown: 20%
- Calculation: \( 325.00 \times 0.20 = 65.00 \)
- New price: \( 325.00 - 65.00 = 260.00 \)

2. **Second Markdown (December):**
- Price after first markdown: $260.00
- Markdown: 10%
- Calculation: \( 260.00 \times 0.10 = 26.00 \)
- Final price: \( 260.00 - 26.00 = 234.00 \)

So, a Christmas shopper in December would pay **$234.00** for the coat.
