The answer is B, because A and C are automatically eliminated because they are subtracting, and the equation that represents the situation is an addition inequality. B is correct because the two parenthesis numbers represents the students attending the fair paying $0.50, and there are 200 students. The 2.25a represents an amount of adults, each paying $2.25.
Answer: B
You have to divide 400 by 5. That will equal 80. Since the ratio is 3:2 Just multiply 3 by 80 then 2 by 80! :-)
You can check it by simplifying it again.

Answer:
2.5
Step-by-step explanation:
A triangle ABC with vertices A(0, 0), B(0, 4), and C(6, 0) is dilated to form a triangle A'B'C' with vertices A′(0, 0), B′(0, 10), and C′(15, 0). If the center of dilation is point A or A' (the origin), then
![\dfrac{A'B'}{AB}=\dfrac{A'C'}{AC}.](https://tex.z-dn.net/?f=%5Cdfrac%7BA%27B%27%7D%7BAB%7D%3D%5Cdfrac%7BA%27C%27%7D%7BAC%7D.)
Since
- AB=4;
- A'B'=10;
- AC=6;
- A'C'=15,
then the scale factor of the dilation is
![k=\dfrac{10}{4}=\dfrac{15}{6}=2.5.](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B10%7D%7B4%7D%3D%5Cdfrac%7B15%7D%7B6%7D%3D2.5.)
