Question

If you pay $107 for groceries including tax, what is the price of groceries before tax when you are taxed at 7%?

Answer 1

100

Explanation:

Original price: x

x + (7%*x) = 107.

107 is 107% of the original price

107 = 1.07x

Divide by 1.07 on both sides

x = 100

Check:

7% of 100 is 7

100 + 7 = 107

Hope this helps :)
