225 + 225*0.35 = x
225 + 78.75 = x
303.75 = x

Step-by-step explanation:
None of the choices is correct. Are you sure that the question was written accurately?
If p is the REGULAR price, not the same price, then there are three correct answers:
sale price = p-0.15p = 0.85p = $420.75
Given:
The equation is:
![x^2-10x=7](https://tex.z-dn.net/?f=x%5E2-10x%3D7)
To find:
The number that should be added to sides of the equation to complete the square.
Solution:
If an expression is in the form of
, then we have to add
to make it perfect square.
We have,
...(i)
To make it perfect square we need to add square of half of coefficient of x on both sides.
Coefficient of x is -10, so square of half of coefficient of x is:
![\left(\dfrac{-10}{2}\right)^2=(-5)^2](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7B-10%7D%7B2%7D%5Cright%29%5E2%3D%28-5%29%5E2)
![\left(\dfrac{-10}{2}\right)^2=25](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7B-10%7D%7B2%7D%5Cright%29%5E2%3D25)
On adding 25 on both sides of (i), we get
![x^2-10x+25=7+25](https://tex.z-dn.net/?f=x%5E2-10x%2B25%3D7%2B25)
![(x-5)^2=32](https://tex.z-dn.net/?f=%28x-5%29%5E2%3D32)
Therefore, we need to add 25 to both sides of the equation to complete the square.
