Answer:
The equation will be : 0.8x – 12
Step-by-Step Explanation:
Let the original price of the jacket be = x
As given, the jacket is on sale of $15 off, so the sale price is = x-15
Its also given that as part of a one-day sale, a 20% discount is applied to all purchases which means that after the 20% discount, the final price will be 0.80 times the sale price.
So, the final price of the jacket will be :
=
(Though options or equations are not given to choose from, but this is the only correct answer.)

<h2>The Third table of ordered pairs represents a proportional relationship.
</h2>
Explanation:
A proportional relationship is defined as the relationship between two quantities where one is directly proportional to another with a proportionality constant.
For example, y = ax
Here a is the proportionality constant.
This expression shows that y varies directly as x varies.
From the tables mentioned in the below attachment, we can easily say that "Table 3" has the ordered pairs which represents proportional relationship.
Table 3 defines y is directly proportional to x with proportionality constant .
