That depends what the rate of tax is.
The easiest way to understand the answer is to turn it around. If you wanted to calculate the item price plus tax, you would multiply the item price by 1.073. So, to back up to the item price from the item price plus tax, divide the item price plus tax by 1.073. $20.00 / 1.073 = item price before sales tax.
$50 plus tax... would mean you pay $50, plus whatever sales tax is charged. So yes, taxes will be included in the final price, which will be more than $50.
The total plus tax should be the total selling price!
$450.00 plus 8.25% tax would be a total of $487.13. This is calculated by multiplying 450 by 0.0825 to determine the tax amount. Then add this to the $450 price.
That depends what the level of tax is. If the tax is 5%, then you would multiply 26.99 by .05 ; this will give you the amount of the tax imposed. You would then add the tax plus your original purchase price to equal your total. ($28.34) If the tax is 9%, you would multiply 26.99 by .09 and so on. ($29.42)
The total tax is $2.57 and the total price with tax is $42.07
The total tax is $1.84 and the total price with tax is $31.22.
The total tax is $3.43 and the total price with tax is $38.43
Five dollars plus tax would be 5 plus whatever the tax percentage is. If the tax is 10%, $5 plus tax would be $5.50.
The total tax is $5.15 and the total price with tax is $67.59
The total tax is $3.43 and the total price with tax is $38.43
The total tax is $4.20 and the total price with tax is $54.20
