Answer: C. 
Step-by-step explanation:
1. You have the following equation of the parabola in Vertex form:

Where h is the x-coordinate of the vextex and k is the y-coordinate of the vextex.
2. You know that the vertex of this parabola is at (-2, 5), then, susbtitute this point into the equation. Then, you obtain:

3. Therefore, the answer is the option C.
Answer:
O.26
Step-by-step explanation:
Divide The cost from the pieces
900/45 = 20
so ratio of middle school students and teachers: 900:45 = 20:1
if high school student-teacher ratio as middle school then
x/110 = 20/1
so x = 110 * 20 = 2200
answer is C) 2200
