Answer: The total price is $ .

Calculation type: Finding the value after a percentage increase (adding tax). The default rate here is only an example — VAT/GST rates vary by country.
Calculator usage:
Step 1: Calculate the tax amount. Use the Basic Percentage Calculator (“What is A% of B?”). Enter 20 [A] and $200 [B]. The calculator will determine 20% of $200.
Step 2: Add the tax amount calculated in Step 1 to the price before tax.
Formula explanation:
We want to find the total price, which is the price before tax plus 20% VAT/GST.
Tax amount = (20 / 100) × $200 = 0.2 × $200 = $40
Total price = $200 + $40 = $240
