To calculate the total price you would pay for the TV antenna, you need to add the sales tax to the original price. Here are the steps:
Calculate the sales tax amount:
Sales Tax = Original Price * (Tax Rate / 100)
In this case, the original price is $38, and the tax rate is 3.5%.
Sales Tax = $38 * (3.5 / 100) = $1.33
Add the sales tax to the original price:
Total Price = Original Price + Sales Tax
Total Price = $38 + $1.33 = $39.33
Therefore, the price you would pay for the TV antenna, including the 3.5% sales tax, is $39.33.
