D. $28.75

Explanation:

To find the final cost, we need to calculate the tip first.

Tip = 15% of $25
Tip = 0.15 x $25
Tip = $3.75

Now, we add the tip to the cost of the haircut:

Final cost = Cost of haircut + Tip
Final cost = $25 + $3.75
Final cost = $28.75

So, Molly's final cost was $28.75.

The total cost is the haircut price plus a 15% tip. Calculating 15% of $25:
$25 × 0.15 = $3.75.
Adding the tip to the original cost:
$25 + $3.75 = **$28.75**.

DeepSeek-Coder-V2 To determine Molly's final cost after leaving a 15% tip on a $25 haircut, we need to calculate the tip amount and then add it to the original cost.

1. Calculate the tip amount:
\[
\text{Tip amount} = 25 \times 0.15 = 3.75
\]

2. Add the tip amount to the original cost:
\[
\text{Final cost} = 25 + 3.75 = 28.75
\]

Thus, the correct answer is:
\[
\boxed{D}
\]

baichuan4 To calculate the final cost, we need to add the cost of the haircut ($25) and the tip (15% of $25).

First, let's calculate the tip:
15% of $25 = 0.15 × $25 = $3.75

Now, let's add the tip to the cost of the haircut:
$25 + $3.75 = $28.75

So, the final cost is $28.75.

Answer: D. $28.75

doubao D. The tip amount is 25 * 0.15 = 3.75. The final cost is 25 + 3.75 = 28.75. D
minimax To calculate the final cost, we need to calculate the tip amount and add it to the original haircut cost.

Tip amount = 15% of $25
Tip amount = 0.15 * $25
Tip amount = $3.75

Now, add the tip amount to the original cost of the haircut to get the final cost:

Final cost = Original cost + Tip amount
Final cost = $25 + $3.75
Final cost = $28.75

The correct answer is:

D. $28.75
D
kimi To calculate the final cost including the tip, you first calculate the amount of the tip and then add it to the original cost.

The tip is 15% of $25, so you calculate it as follows:
\[ \text{Tip} = 25 \times \frac{15}{100} = 25 \times 0.15 = 3.75 \]

Now, add the tip to the original cost:
\[ \text{Final Cost} = 25 + 3.75 = 28.75 \]

So the correct answer is:
D. $28.75
