Answer:
Sarah have
bottle of water.
Step-by-step explanation:
We are given that,
Total number of bottles = 5
As, each bottle is divided into 4 portions.
The amount of water per person = 
Further, Sarah took 1 portion from each bottle and there are 5 bottles.
So, the amount of water Sarah have =
= 
Hence, Sarah have
bottle of water.
Answer:
k = 5,
y = 5x
Step-by-step explanation:
If y is proportional to x,
y ∝ x
Then the equation will be
y = kx
Her k = proportionality constant.
Now we choose a point from the given table.
Let the point is (2, 10).
By putting the values of x and y in the equation,
10 = 2×k
k = 
k = 5
This will be true for any point we choose from the table.
And the equation will be y = 5x
X= -2 or X= 3 either one works.
