How much is 84 plus tax?

Answer 1

In order to properly answer this question, I'd have to know how much the tax is. However, all taxes are a percentage of the initial price, so to help the questioner out, let's assume that the tax is 10%.

10% of 84 is 8.4

(First convert the percentage to decimal and multiply by the price: .1 x 84=8.4)

Then you add the 8.4 to the 84:

84+8.4=92.4

If you have another tax amount, such as 8%, follow the same formula:

.08 x 84=6.72 => 84+6.72=90.72

etc, etc
