Question

A pack of cinnamon-scented pencils sells for $8.00. What is the sales tax rate if the total cost of the pencils Is $8.56 The sales tax rate is ___%

Answer 1

To find the tax rate we can use the rule of three.

`\begin{gathered} 8\rightarrow100 \\ 8.56\rightarrow x \end{gathered}`

Then,

`x=(8.56\cdot100)/(8)=107`

Now, since 8.56 dollars represents 107% of the prices, this means that the tax rate is 7.
