Valentina purchased three shirts for $$15.99 each two pairs of pants for $25 each in a pair of shoes for $39.99 each. The sales tax is 5% How much did she pay?

Answer 1

To find out how much Valentina paid in total, we will calculate the cost of the shirts, pants, and shoes, and then add the sales tax.

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

2. **Calculate the total cost of the pants:**
\[
\text{Cost of pants} = 2 \times 25 = 50.00
\]

3. **Calculate the total cost of the shoes:**
\[
\text{Cost of shoes} = 1 \times 39.99 = 39.99
\]

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

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

6. **Calculate the total amount paid including tax:**
\[
\text{Total amount paid} = \text{Total cost} + \text{Sales tax}
\]
\[
\text{Total amount paid} = 137.96 + 6.898 = 144.858
\]

Rounded to two decimal places, Valentina paid:
\[
\text{Total amount paid} \approx 144.86
\]

Therefore, Valentina paid **$144.86**.
