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_{} \\ (1.06x)/(1.06)=(22.26)/(1.06) \\ x=21 \end{gathered}`

2) Then the original price was $21
