how to figure how much sales tax paid when only gross amount?

Question

is knon...rate is 9.25 ...

Answer 1

You mean you have the total amount paid - taxes and cost?

Divide the amount by 1.0925.

The gross amt. represents the cost + 9.25% or 109.25% of the purchase price. You would multiply the purchase price by 109.25 to get the total cost, so you will divide the total cost by 109.25% to find the purchase price.
