Question

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

Answer 1

so the price is 10.99, up with the tax goes to 11.53, so the tax amount is really 11.53 - 10.99, or $0.54, 54 cents.

now, if we take 10.99 to be the 100%, what is 0.54 in percentage off of it?


`\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 10.99&100\\ 0.54&t \end{array}\implies \cfrac{10.99}{0.54}=\cfrac{100}{t}\implies t=\cfrac{0.54\cdot 100}{10.99}`
