Question

What is the sales tax on a scanner priced at $190 if the sales tax rate is 5.9%?

Answer 1

To compute the sales tax, we need to calculate the 5.9% of $190. We can do this with a proportion, where $190 represents 100%, and x represents 5.9%, that is:

`\frac{190\text{ \$}}{x\text{ \$}}=\frac{100\text{ \%}}{5.9\text{ \%}}`

Solving for x:

`\begin{gathered} 190\cdot5.9=100\cdot x \\ (1121)/(100)=x \\ 11.21=x \end{gathered}`

The sales tax is $11.21
