Calculating Sales Tax

Let's say you decided the cost of the board game is **$15.50**.

Now, we'll choose **Wisconsin** as the state for this example.

### Step 1: Research the Sales Tax
As of October 2023, the general state sales tax rate in Wisconsin is **5.0%**.

### Step 2: Calculate Sales Tax
To calculate the sales tax, use the formula:

\[
\text{Sales Tax} = \text{Cost of Item} \times \text{Sales Tax Rate}
\]

Substituting in the values we have:

\[
\text{Sales Tax} = 15.50 \times 0.05 = 0.775
\]

### Step 3: Calculate Total Cost
Now, add the sales tax to the initial cost of the board game:

\[
\text{Total Cost} = \text{Cost of Item} + \text{Sales Tax}
\]

Substituting the values:

\[
\text{Total Cost} = 15.50 + 0.775 = 16.275
\]

Since prices are usually rounded to two decimal places, we round the total cost:

\[
\text{Total Cost} \approx 16.28
\]

### Final Answer
The total cost of the board game in Wisconsin, including sales tax, is approximately **$16.28**.
