Final answer:
To calculate the sales tax on an item, convert the tax rate to a decimal and multiply by the item's cost. Without the actual sales tax rate, it's not possible to provide the exact amount for the $14.50 item.
Step-by-step explanation:
To determine the sales tax for an item priced at $14.50, we first need to know the sales tax rate, which is not provided in the question. However, using the examples provided, we can infer a method to calculate the sales tax once we have that rate. To find the sales tax amount, we convert the tax rate from a percentage to a decimal and then multiply it by the item's cost.
Here's the formula: Sales Tax = Price Before Tax x (Sales Tax Rate as a Decimal).
For instance, if the sales tax rate were 7%, we would calculate the sales tax on a $14.50 item as follows:
$14.50 x 0.07 = $1.015.
After rounding to the nearest cent, the sales tax would be $1.02.
Without the actual sales tax rate, we cannot determine which option (a, b, c, or d) is correct. If you have the tax rate, you can use the formula above to find the exact tax amount.
