Step-by-step explanation:
To calculate the sales tax on a total of $7.33 when the tax rate is 3%, convert the percent to a decimal by dividing by 100. This gives us a decimal rate of 0.03. Then, multiply the total cost by the decimal sales tax rate to find the amount of tax.
Here's the calculation:
- Sales Tax Rate = 3% = 0.03 (after conversion)
- Total Cost = $7.33
- Amount of Sales Tax = Total Cost × Sales Tax Rate
- Amount of Sales Tax = $7.33 × 0.03
- Amount of Sales Tax = $0.2199
Round the result to the nearest cent to get the sales tax amount. Rounding $0.2199 gives us $0.22. So, the amount of sales tax is $0.22.
