an item has a listed price of $30. if the sales tax rate is 7%, how much is the sales tax (in dollars)? sales tax: $
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:
$2.1$
