Answer 1

To calculate Valentina's total cost including tax, we need to determine the total cost of her purchases before tax and then add the sales tax.

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

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

3. **Calculate the total cost of the shoes:**
\[
\text{Total cost of shoes} = 39.99
\]

4. **Calculate the total cost before tax:**
\[
\text{Total cost before tax} = 47.97 + 50.00 + 39.99 = 137.96
\]

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

6. **Calculate the total cost including tax:**
\[
\text{Total cost including tax} = 137.96 + 6.898 \approx 144.86
\]

Therefore, the total amount Valentina paid is **$144.86**.
