Answer:
After the coupon and sales tax were applied, he paid $15.27 for the shirt.
Explanation:
We are given that a shirt is $16.95. This is reduced by 15% due to the coupon.
![100\% - 15\% = 85\%](https://img.qammunity.org/2021/formulas/mathematics/high-school/bv0b8xnx47ke5bmb1kz9ie91vrhlnjo39r.png)
Therefore, 85% of the shirt price is still active.
![\displaystyle (85)/(100)=0.85](https://img.qammunity.org/2021/formulas/mathematics/high-school/dnp3swu7lqbhujly6s36ut0lnp6c7da0vf.png)
We can multiply this value by the shirt price to find the current price.
![16.95 * 0.85 = 14.4075 \approx \$14.41](https://img.qammunity.org/2021/formulas/mathematics/high-school/vb1dwofyj399y1i4672w17ex81q6kiqbo9.png)
However, the shirt also has a sales tax of 6% applied after the coupon.

Now, we need to find the total price for the shirt.
![\displaystyle 14.41 * 1.06 = 15.2746 \approx \$15.27](https://img.qammunity.org/2021/formulas/mathematics/high-school/2q2k9am8xhggnjes9nes1x2d9bkfyt181i.png)
Therefore, he paid $15.27 for the shirt.
