The answer to this equation is 40.
First we need to found out how much you could buy WITHOUT coupon,
which is 2 shirts that cost $ 22.
You will have $5 Leftover.
Since you have a $6 dollar off coupon, you could buy one more t-shirt with
$ 5 (11 - 6 = 5)
So, the amount of t-shirt you could buy WITH coupon is 3 T-shirts.
Answer:
Dependent: Cost
Independent: Number of shirts
Step-by-step explanation:
For this case we have that by definition, the equation of the line in a slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have the following equation:

Thus, the slope is 
By definition, if two lines are perpendicular then the product of the slopes is -1.

We find

Thus, the equation of the line is:

We substitute the given point to find "b":

Thus, the equation of a line perpendicular to the given line and passing through the given point is:
