Final answer:
To find the sales tax due on a $222 antique with a 9.4% sales tax rate, multiply the price by the sales tax rate (converted to decimal), resulting in $20.868. After rounding to the nearest cent, the sales tax due is $20.87.
Step-by-step explanation:
To determine how much sales tax will be due on an antique with a price tag of $222 and a county sales tax rate of 9.4%, you first need to convert the percentage rate to a decimal. The decimal form of 9.4% is 0.094. Next, you multiply the price of the item by the decimal rate to find the amount of sales tax.
The calculation will look like this:
$222 × 0.094 = $20.868
When calculating sales tax, it's common practice to round to the nearest cent. Therefore, the sales tax due would be $20.87.
Remember to add the sales tax to the original amount to get the final amount that needs to be paid, which is an important step especially in financial transactions involving sales tax.
