To estimate the sales tax and final cost of a book that costs $12.99 with a sales tax of 6%, follow these steps:
Step 1: Calculate the sales tax amount.
Sales tax is usually expressed as a percentage of the original price. To find the sales tax amount, multiply the original price by the sales tax rate (as a decimal).
In this case:
Sales tax amount = $12.99 * 0.06 = $0.7794 (rounded to two decimal places)
Step 2: Calculate the final cost.
To determine the final cost, add the sales tax amount to the original price.
In this case:
Final cost = $12.99 + $0.7794 = $13.7694 (rounded to two decimal places)
Therefore, the estimated sales tax for the book is approximately $0.78, and the final cost would be approximately $13.77.
