To calculate the sales tax, you can use the following formula:
\[ \text{Sales Tax} = \text{Taxable Amount} \times \left(\frac{\text{Sales Tax Percentage}}{100}\right) \]
Given that the taxable amount is $142 and the sales tax percentage is 7%, the calculation would be:
\[ \text{Sales Tax} = 142 \times \left(\frac{7}{100}\right) \]
Calculating it step by step:
-
Convert the percentage to decimal: \[ \frac{7}{100} = 0.07 \]
-
Multiply: \[ \text{Sales Tax} = 142 \times 0.07 = 9.94 \]
Thus, the amount of the sales tax is $9.94.
