To determine the sales tax, we have to compute the 5.2% of 272.26. To determine the x% of y, we use the following expression:
[tex]y*\frac{x}{100}.[/tex]Therefore, the 5.2% of 272.26 is:
[tex]272.26*\frac{5.2}{100}.[/tex]Simplifying the above result, we get:
[tex]sales\text{ tax}\approx14.16.[/tex]
