Answer:
The cost of each bag of chip is $0.85
Step-by-step explanation:
Given as :
The cost of one juice pouch = $1.25
The number of juice pouch = 2
The number of chips bag bought = 3
The total cost of 2 juice pouch and 3 chips bag = $5.05
Let The cost of each bag of chip = $c
<u>Now, According to question</u>
cost of one juice pouch × number of juice pouch + cost of each chips bag × number of chips bag = Total cost of both items
Or, $1.25 × 2 + $c × 3 = $5.05
Or, $2.5 + $c × 3 = $5.05
Or, $c × 3 = $5.05 - $2.5
Or, $c × 3 = $2.55
∴ c =
i.e c = $0.85
So, The cost of each bag of chip = c = $0.85
Hence,The cost of each bag of chip is $0.85 Answer
Notice that our function 
is a parabola, and the vertex form of a parabola is:
where (h,k) are the coordinates of its vertex.
The first thing we need to do is find the vertex (h,k) and to do that we are going to use the vertex formula:
, and then we are going to evaluate our function at 
to find 
.
We know for our problem that
, and 
, so lets replace those values in our vertex formula to find :
Now, we are going to evaluate our function at -6 to find:
Now that we have our vertex, where and ; lets replace those values in our vertex form equation:
![f(x)=-5[x-(-6)]^{2} +(-1)](https://tex.z-dn.net/?f=f%28x%29%3D-5%5Bx-%28-6%29%5D%5E%7B2%7D%20%2B%28-1%29)
We can conclude that the vertex form of our function is, and its vertex is (-6,-1).
