Answer: The required amount of sales tax is $2.97.
Step-by-step explanation: Given that Cassie wants to buy a pair of shoes for $26.50 and a shirt for $9.50 and the sales tax rate is 8.25%.
We are to find the amount of sales tax on Cassie's purchase.
The total amount of purchase is given by
[tex]T_p\\\\=\textup{cost of pair of shoes}+\textup{cost of the shirt}\\\\=26.50+9.50\\\\=36.[/tex]
Therefore, the amount of sales tax is given by
[tex]8.25\%\times T_p\\\\=\dfrac{8.25}{100}\times36\\\\\\=\dfrac{297}{100}\\\\=2.97.[/tex]
Thus, the required amount of sales tax is $2.97.
