Question

You buy a bicycle helmet for $22.26, which includes 6% sales tax. What is the original price of the bicycle helmet before the sales tax?

Answer 1

$21

1) We can tackle this question by writing out an equation considering that the $22.26 is the price with tax in it:

$\begin{gathered} (1.06)x=22.26_{} \\ \frac{1.06x}{1.06}=\frac{22.26}{1.06} \\ x=21 \end{gathered}$

2) Then the original price was $21
