Answer: the pre-tax subtotal is $330

Step-by-step explanation:

Let x represent the pre tax total

If the tax rate in the area is 8.2%, it means that the amount of tax paid is

8.2/100 * x = 0.082x

pretax total + tax = after tax subtotal

Given that after tax subtotal is $357.06, then

x + 0.082x = 357.06

1.082x = 357.06

x = 357.06/1.082

x = 330

the pre-tax subtotal is $330
