-3x^2 + 12x -6
a = -3
b = 12
We calculate the vertex "x" value with this formula:
(vertex "x value") = -b / (2*a)
(vertex "x value") = -12 / -6
The vertex "x" value equals the axis of symmetry value.
The axis of symmetry is at x = 2.

Answer:
The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2
Step-by-step explanation:
Let
x ----> the unit cost of one toy reindeer
y ----> the unit cost of one box of cookies
we know that
----> equation A
----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
The solution is the point (3,2)
see the attached figure
therefore
The unit cost of one toy reindeer is $3 and the unit cost of one box of cookies is $2
