Answer:
To calculate the total cost of the firepit, you need to add the sales tax to the original price.
First, let's calculate the sales tax amount.
Sales tax rate: 8 1/4% = 8.25% = 0.0825 (in decimal form)
Sales tax amount = 0.0825 * $162.95 = $13.45 (rounded to two decimal places)
Now, add the sales tax amount to the original price:
Total cost = $162.95 + $13.45 = $176.40
Therefore, the total cost of the firepit, including sales tax, is $176.40.
