Answer 1

To calculate the total cost of the item including sales tax, you can follow these steps:

1. Calculate the sales tax amount by multiplying the item price by the sales tax rate.
2. Add the sales tax amount to the original price.

Here’s how you do it:

1. **Original price of the item**: $13.73
2. **Sales tax rate**: 7% = 0.07

**Sales tax amount**:
\[
\text{Sales tax amount} = \text{Original price} \times \text{Sales tax rate} = 13.73 \times 0.07 = 0.9611
\]

3. **Total cost including sales tax**:
\[
\text{Total cost} = \text{Original price} + \text{Sales tax amount} = 13.73 + 0.9611 \approx 14.69
\]

So the total cost including sales tax is approximately **$14.69**.

The correct answer is **B. $14.69**.
