Answer

Explanation:

Step1: Convert percentage to decimal

To find the sales - tax amount, we first convert the 7% sales - tax rate to a decimal. We do this by dividing the percentage by 100. So, $7%=\frac{7}{100}=0.07$.

Step2: Calculate sales - tax amount

We multiply the listed price of the item by the sales - tax rate (in decimal form). The listed price is $30, and the sales - tax rate is 0.07. So the sales - tax amount is $30\times0.07 = 2.1$.

Answer:

$2.1$
