Understanding Sales Tax Calculation

The video tutorial explains how to calculate the total cost of an item including sales tax. It begins by identifying the key information needed, such as the price of the item and the sales tax percentage. The tutorial then demonstrates how to calculate the sales tax by converting the percentage into a decimal and multiplying it by the item's price. After obtaining the tax amount, the video shows how to round the result to two decimal places, as is standard for monetary values.
