Answer: The total price is $ .

Calculation type: Finding the value after a percentage increase (adding tax). The default rate here is only an example — sales tax varies by state and locality.
Calculator usage:
Step 1: Calculate the tax amount. Use the Basic Percentage Calculator (“What is A% of B?”). Enter 8 [A] and $200 [B]. The calculator will determine 8% of $200.
Step 2: Add the tax amount calculated in Step 1 to the pre-tax price.
Formula explanation:
We want to find the total price, which is the pre-tax price plus 8% sales tax.
Tax amount = (8 / 100) × $200 = 0.08 × $200 = $16
Total price = $200 + $16 = $216
