Price before tax

Question

You just paid $310.25 for an item that included a sales tax of 7%. What was the price of the item before tax? Show all work.

Answer 1

The total price represents the price before tax plus a percentage of this added as tax.  In this case, if the price before tax is x, then x + .07x = 310.25, or 1.07 x = 310.25.

 

Then x = 310.25/1.07 = 289.95
