1. Identify the Purchase Amount and Sales Tax Paid:
- The purchase amount is [tex]$20.50.
- The sales tax paid is $[/tex]1.64.
2. Calculate the Sales Tax Rate:
You can find the sales tax rate by dividing the sales tax paid by the purchase amount. This will give you the rate as a decimal.
[tex]\[
\text{Sales Tax Rate} = \frac{\text{Sales Tax Paid}}{\text{Purchase Amount}} = \frac{1.64}{20.50}
\][/tex]
3. Convert the Sales Tax Rate to a Percentage:
To express the sales tax rate as a percentage, multiply the rate in decimal form by 100.
[tex]\[
\text{Sales Tax Percentage} = \text{Sales Tax Rate} \times 100
