The answer is A.
We know that p must be larger than d since a discount means something will be cheaper. Then we know that $2.50 is essentially what p-d should equal to (p-d =2.50)
Then you work through the various tables and find which values will consistently give you 2.50 as the difference between p and d.
For example in table A:
3.00-0.15=2.50
4.00-1.50=2.50
5.00-2.50=2.50
6.00-3.50=2.50
Answer:
1
Step-by-step explanation:
Given triangle ABC with vertices at points A(2,-4), B(4,-4) and C(4,-2).
1. Rotate this triangle anticlockwise by 90° angle over the origin. This rotation has the rule

then

2. Reflect triangle A'B'C' across the y-axis. This reflection has the rule

then

These are vertices of triangle 1
X^2+4x+4 and there is no remainder
