Answer 1

To find the total amount Valentina paid, we will first calculate the total cost of the shirts, pants, and shoes before tax, and then add the sales tax.

1. **Calculate the total cost of the shirts:**
\[
\text{Cost of shirts} = 3 \text{ shirts} \times 15.99 = 47.97
\]

2. **Calculate the total cost of the pants:**
\[
\text{Cost of pants} = 2 \text{ pairs} \times 25.00 = 50.00
\]

3. **Cost of the shoes:**
\[
\text{Cost of shoes} = 39.99
\]

4. **Total cost before tax:**
\[
\text{Total cost before tax} = \text{Cost of shirts} + \text{Cost of pants} + \text{Cost of shoes}
\]
\[
= 47.97 + 50.00 + 39.99 = 137.96
\]

5. **Calculate the sales tax:**
\[
\text{Sales tax} = 137.96 \times 0.05 = 6.898
\]

6. **Total cost including tax:**
\[
\text{Total cost} = \text{Total cost before tax} + \text{Sales tax}
\]
\[
= 137.96 + 6.898 = 144.858
\]

Rounded to two decimal places, the total cost is:
\[
144.86
\]

Thus, Valentina paid **$144.86**.

The correct response is: **$144.86**.
