Final answer:
To find the sales tax, convert 13% to a decimal (0.13) and multiply it by the original price ($50.22). The sales tax comes to $6.53, which when added to the original price results in a selling price of $56.75.
Step-by-step explanation:
Finding the Amount of Sales Tax and the Selling Price
To calculate the amount of sales tax for an item, you need to first convert the given percentage to a decimal. In this case, a 13% sales tax rate is equivalent to 0.13. Then, you multiply this decimal by the original price of the item.
For an original price of $50.22, the equation will be:
Sales Tax = $50.22 × 0.13
After calculating the amount of sales tax, it will then be added to the original price to find the total selling price.
For the original price of $50.22, the sales tax is $50.22 × 0.13, which is $6.5286.
After rounding to the nearest cent, the sales tax is $6.53. To get the selling price, add the original price to the sales tax: $50.22 + $6.53 = $56.75.
Therefore, the total amount of tax is $6.53 and the selling price of the item is $56.75.
