Answer:
$34.02
Explanation:
10% off means that the price of the shirt is now 100% - 10% = 90%
The price of one shirt now is
[tex]\frac{90}{100}\times12=10.8[/tex]Furthermore, 5% sales tax means that the price will be 100% + 5% = 105% higher
The price of the shirt after tax will be
[tex]\$10.8\times\frac{105\%}{100\%}[/tex]
