Question

The sales tax is $43 on the purchase of a dining room set for $860. Find the sales tax rate. The sales tax rate is ...%

Answer 1

Step1: Write out the giving parameters

`\begin{gathered} \text{sales tax=\$43} \\ \text{Purchasing value=\$860} \end{gathered}`

Step2: Write out the formula

`\text{sales tax rate =}\frac{sales\text{tax}}{purcha\sin g\text{ value}}\text{ }`

Step3: Substitute the parameter into the formula

`\text{sales tax rate=}(43)/(860)=(1)/(20)`

Then in percentage, the sales tax rate becomes

`(1)/(20)*100=5\text{ \%}`

Therefore the sales tax rate is 5 %
