Given:
Coupon = 30%
Amount paid after using the coupon = $28
Let's find the regular price.
The coupon is a form of voucher that enables someone to get a discount off a product.
This means after a discount of 30%, the new price of the jeans is $28
Thus, to find the regular price, we have:
![28=P(1-(30)/(100))](https://img.qammunity.org/2023/formulas/mathematics/college/17e6mdykalx4mnnf8c08elxjw4ef0ewwth.png)
Where P represents the regular price.
From the equation above, let's solve for P.
![28=P(1-0.3)](https://img.qammunity.org/2023/formulas/mathematics/college/btm74ml540i5vqxrds53hf0e5d3r443goc.png)
![\begin{gathered} 28=P(0.7) \\ \\ 28=0.7P \\ \\ \text{Divide both sides by 0.7:} \\ (28)/(0.7)=(0.7P)/(0.7) \\ \\ 40=P \\ \\ P=40 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/hh0na7ai1gwkaunido8js0224f9gi7jho4.png)
Therefore, the regular price for the Jeans is $40

$40
