Total bill would be excluding the discount, so Deens has included the discount on the wrong side of the equation.
So: 9X = 88-25
9X=63
63/9=7
therefore Deens bought 7 shirts
Answer:
5
Step-by-step explanation:
Divide

then multiply the divide awnswer and multiply by 3
First, let us solve for the slope of the line which it
intersects with:
m’ = (y2 – y1) / (x2 – x1)
m’ = (-3 – 4) / (-2 – 5)
m’ = 1
The slope of the perpendicular line is the negative
reciprocal, therefore:
m = - 1 / m’
m = - 1 / 1
m = -1
<span>So the slope of the line is -1.</span>
