Question

A pair of gloves were tagged at 10.99 and after tax cost 11.53 what was the percent of sales tax

Answer 1

Given, before tax amount, P=10.99.

After tax amount, A=11.53.

Let R be the percent of sales tax.

`\begin{gathered} A=P*(100+R)/(100) \\ 11.53=10.99*((100+R)/(100)) \\ (11.53*100)/(10.99)=100+R \\ 104.91=100+R \\ 4.91=R \end{gathered}`

Therefore, 4.91% is the rate of sales tax.
