If the price of a dress is $40 before tax is added on and tax is $20, what will the final price of the dress be?

To determine the final price of the dress, you need to add the original price of the dress to the tax amount.

Here’s the calculation:

Original price of the dress: $40

Tax: $20

Final price = Original price + Tax

Final price = $40 + $20

Final price = $60

Therefore, the final price of the dress after adding the tax is $60.
