Question

Answer 1

Let x be the percentage of the sales tax rate as a decimal number, then we can set the following equation:

`360x=21.60.`

Dividing by 360 we get:

`\begin{gathered} (360x)/(360)=(21.60)/(360), \\ x=0.06 \end{gathered}`

Therefore, the sales tax rate as a percentage is 6%.

Answer: 6%.
