Answer:
$33
Explanation:
Given: Addy had 20% off coupon.
The coupon took $8.25 off of the shirt price.
Lets assume the original cost of shirt be "x".
We know Addy had 20% off coupon, which help to reduce the price of shirt by $8.25.
∴ We can form an equation to know the original price of shirt.
⇒
![(20)/(100) * x= \$ 8.25](https://img.qammunity.org/2021/formulas/mathematics/middle-school/bjbkbq8cc6b21snecdl94uai3shwbmacpw.png)
⇒
![(1)/(5) * x= \$ 8.25](https://img.qammunity.org/2021/formulas/mathematics/middle-school/19xuwt5375uad0k55lhl7wyumx1x3mr0ji.png)
Multiplying both side by 5
⇒
![x= 8.25* 5](https://img.qammunity.org/2021/formulas/mathematics/middle-school/cec1dr8lfa6r7z6zf6pg1ji57qvh0kxnek.png)
∴
![x= \$ 41.25](https://img.qammunity.org/2021/formulas/mathematics/middle-school/hfo45xdjyqf5vb50tnzqqeg3gfgr2r44p3.png)
Hence, The original cost price of shirt was $41.25.
Next, finding the price paid by Addy for her new shirt by reducing coupon discount from the cost of shirt.
Price paid by Addy for her new shirt=
![\$ 41.25- \$ 8.25= \$ 33](https://img.qammunity.org/2021/formulas/mathematics/middle-school/jewutys1zpbdvayilq6x59k6wmiukk1icf.png)
Hence, Addy paid $33 for her new shirt.
