That is incorrect. If you multiply the "total amount left after tax" by the tax rate (1.072) you should arrive at $3,227.39. In the answer above, you don't arrive at that total so the logic is incorrect.
You take the total sum and divide by 1.072 which equals: $3,010.625. This is the new sub total, which means the tax is actually $216.765. To prove the math, take $3,010.625 and multiply by 1.072 and you arrive at the total after tax.
