pdf Sales Tax - Grand Total

This consumer math worksheet provides structured practice calculating sales tax and determining the grand total of a purchase. A clearly modeled example demonstrates how multiplying by 1.05 represents adding 5% sales tax to the original price. Students learn that if sales tax is 5%, the total cost is 105% of the original price, which can be written as the decimal 1.05 and multiplied directly by the item’s cost.

Students then complete 10 practice problems involving realistic purchase amounts. For problems 1–5, students apply an 8% sales tax. For problems 6–10, students apply a 6% sales tax. Each problem requires calculating the tax amount and/or multiplying by the equivalent decimal (such as 1.08 or 1.06) to determine the grand total. Students are instructed to round to the nearest penny when necessary, reinforcing precision with decimal multiplication and money.

Because the worksheet emphasizes the connection between percent, decimal form, and total cost, it strengthens proportional reasoning and financial literacy. It works well as guided instruction, independent practice, homework, small-group intervention, or assessment preparation in a unit on percent of a number and consumer applications.
