A man realizes he lost the detailed receipt from the store and only has the credit card receipt with theafter-tax total. If the after-tax total was $357.06, and the tax rate in the area is 8.2%, what was the pre-tax subtotal?

Respuesta :

Answer: the pre-tax subtotal is $330

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
