Answer:
Option c is right.
Step-by-step explanation:
Given is a parabola y =x^2
From that transformation is done to get parabola as
y =(0.2x)^2
We find that instead of x here we use 0.2x
i.e. New x = 5 times old x
Hence there is a horizontal expansion of scale factor 5.
We can check with any point also
When y =4, x=2 in the parent graph
But when y =4 , we have x = 10 in the new graph
i.e. there is a horizontal expansion of scale factor 5.
53.35/11 = 4.85 for 1 key chain
4.85 *4 = 19.40
Now:
kimberly = k
jordan = k - 102

kimberly = k - 2
jordan = k - 104
k - 2 = 4(k - 104)
k - 2 = 4k - 416
-3k = -414
k = 138
kimberly is 138
jordan is 138 - 102 = 36
k - 102 = 36
