We will see that the price of the bike helmet without the tax is $50
How to find the original price?
Let's define P as the original price, this is the 100%.
We know that a tax rate of the 9% is equal to $4.50, then we can write two equations:
100% = P
9% = $4.50
We can take the quotient between these two equations and solve that for P, we will get:
(100%/9%)*$4.50 = P = $50
So the price of the helmet, without tax, is $50.
