Definition

Calculating tax involves determining the percentage amount to be added to the base price of a product or service.

Description

Calculating tax is a fundamental application of percentages in real-world scenarios. When purchasing goods or services, the total cost is often the sum of the base price and the tax applied. Understanding how to calculate tax is essential for budgeting and financial literacy.

For example, if a product costs $50 and the tax rate is 8%, the tax amount is calculated as 

50 × 0.08 = 4

Therefore, the total cost is 

50 + 4 = 54

In math education, learning to calculate tax helps students understand the practical applications of percentages and develop skills in financial mathematics. This knowledge is crucial for everyday transactions and financial planning.

Teacher’s Script: "Let's say you buy a book for $30 and the sales tax rate is 5%. To find the total cost, first calculate the tax: 30 × 0.05 = 1.5. Add this to the original price: 30 + 1.5 = 31.5. So, the total cost is $31.50."
