- Identify the base price of the repair at Store A: \(\$1,200\).
- Convert the tax rate from a percentage to a decimal: \(6\% = 0.06\).
- Multiply the base price by the decimal tax rate to find the tax: \(\$1,200 \times 0.06 = \boxed{\$72}\).
Explanation
- Analysis of the problem
To find the sales tax amount charged at Store A, we start by identifying the relevant financial data from the provided table. For Store A, the base cost of the computer repair is \(\$1,200\), and the applicable sales tax rate is \(6\%\). The other information, such as the costs at Store B, the gratuity percentage, and the shipping terms, is not needed for this specific calculation.
- Calculation of the sales tax
The sales tax amount is calculated by applying the sales tax rate to the base cost of the service. We convert the percentage to a decimal by dividing by 100: \(6\% = \frac{6}{100} = 0.06\). The formula for the sales tax is the product of the base price \(P\) and the tax rate \(r\):
\[\text{Sales Tax} = P \times r\]
Substituting the known values:
\[\text{Sales Tax} = \$1,200 \times 0.06\]
Performing the multiplication:
\[\text{Sales Tax} = \$72\]
Therefore, the amount of sales tax charged on the computer repair at Store A is \(\$72\).
Examples
Calculating sales tax is a fundamental skill for managing personal finances and understanding the final costs of goods and services. For instance, when purchasing electronics, clothing, or services like car maintenance, you can use the same method to anticipate your total bill. Knowing how to compute this ensures you can effectively budget and double-check your receipts for accuracy.
