Forward and reverse sales tax
Given a pre-tax price and a rate, the total is price × (1 + rate). If you only have the receipt total and want the pre-tax price, divide by (1 + rate). US sales tax rates vary widely by state, county, and city; some categories (groceries, clothing) are exempt in some jurisdictions.
