Let's solve your problem step by step.
1. **Cost of the Board Game:** $13.99
2. **Chosen State:** Wyoming
3. **Sales Tax Rate in Wyoming:** The general state sales tax rate in Wyoming is 4%.
4. **Calculate the total cost including sales tax:**
- First, calculate the sales tax:
\[
\text{Sales Tax} = \text{Cost of the Board Game} \times \text{Sales Tax Rate}
\]
\[
\text{Sales Tax} = 13.99 \times 0.04 = 0.5596
\]
Rounding this to two decimal places, the sales tax is approximately $0.56.
- Then, calculate the total cost:
\[
\text{Total Cost} = \text{Cost of the Board Game} + \text{Sales Tax}
\]
\[
\text{Total Cost} = 13.99 + 0.56 = 14.55
\]
5. **Final Answer:**
- The total cost of the board game, including sales tax, is **$14.55**.
