You buy a shirt originally marked at $16.99. It is on sale for 25% off, and sales tax is 7.5%. How much do you pay?

The cost of the shirt after the given discount is,

`\begin{gathered} C=(1-(25)/(100))16.99 \\ =12.7425 \end{gathered}`

The fiinal cost of the shirt after sales tax is,

`\begin{gathered} FC=(1+(7.5)/(100))C \\ =(1.075)(12.7425) \\ =13.6981875 \\ \approx13.70 \end{gathered}`

Thus, the final cost of the shirt is $13.70.
