Exhibit: A JSON snippet representing a product configuration in Dynamics 365 Commerce.

Refer to the exhibit. A product has a tax group of 'WA' and a tax rate of 0.087. The price is set to 29.99. A customer in Washington state purchases this product. What will be the final price including tax?

⚠ Common exam trap

The trap here is that candidates often forget to round the tax amount to two decimal places before adding it to the price, leading them to choose $32.59 (truncation) instead of the correctly rounded $32.60.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

$32.60

The final price including tax is calculated by adding the tax amount to the base price. The tax amount is $29.99 * 0.087 = $2.60913, which rounds to $2.61 (standard rounding to two decimal places). Adding this to $29.99 gives $32.60. Dynamics 365 Commerce applies tax rounding based on the system's tax calculation settings, typically rounding to the nearest cent.
