S = sale price (in dollars)
p = sticker price (in dollars)
Note: the sticker price is what the customer pays after the discount
Another note: This is ignoring any taxes or other fees
We're told that the sale price is the result of taking 10% off the sticker price. This means...
sale price = (sticker price) - (10% of sticker price)
s = p - 0.10*p
s = 1*p - 0.10*p
s = (1 - 0.10)*p
s = (0.90)*p
s = 0.90*p
So the expression for the sale price is 0.90*p where p is the sticker price in dollars.
Note: this means that the sale price is 90% of the sticker price.
----------------------------------------
Now plug in the sticker price p = 80 to find the sale price s
s = 0.90*p
s = 0.90*80
s = 72
The sale price is $72 which is what the customer will pay (if we ignore any taxes or other fees).

Step-by-step explanation
The first thing you do is plug in zero for y the you solve it
The given equation when you plug 0 in for y is
0=-5x²+25x+70
The value of x = 2.5
The side length of the square = 7.1 units
<h3>How to Find the Perimeter of a Square?</h3>
A square has four congruent sides that are all of the same length. If "s" represents the length of one of the sides of the square., the formula that can be used to find the perimeter of the square is given as:
Perimeter of square = 4(s).
In the given image, we have the following:
Perimeter of the square = 28.4 units
Side length of the square (s) = 3.6x - 1.9
Therefore, we would create the following equation using the perimeter formula:
4(3.6x - 1.9) = 28.4
14.4x - 7.6 = 28.4
14.4x - 7.6 + 7.6 = 28.4 + 7.6
14.4x = 36
14.4x/14.4 = 36/14.4
x = 2.5
Side length of the square = 3.6x - 1.9 = 3.6(2.5) - 1.9
Side length of the square = 7.1 units
