The better buy would be the 36 bottles of water for 4$ because it would be 9 bottles per dollar other than the 24 which is 8 bottles per every dollar. Hope it helps!

-6 -8=-14C. When you subtract from a negative number the product will be smaller than when you started. Sometimes it helps to draw a number line and count that way.

Find the constant of proportionality (k). Using the value for k, enter an equation in the form of y = kx.

Answer:

k = 4, y = 4x

Step-by-step explanation:

From the question, we get the ratio of :

x : y = 1 : 4

Two variables are proportional to each other if their ration is constant. The constant value is denoted by 'k' and is called as constant of proportionality.

In the question, the two variables are :

x = glasses of lemonade

y = lemons used

From the question, the ratio of y is to x is given by :

y : x is 24 : 6 = 4 : 1 or 24/6 = 4

32 : 8 = 4 : 1 or 32/8 = 4

28 : 7 = 4 : 1 or 28/7 = 4

8 : 2 = 4 : 1 or 8/2 = 4

16 : 4 = 4 : 1 or 16/4 = 4

So here the constant is 4 . Therefore, the constant of proportionality, k is 4.

So we can write the equation as :

y = kx

or y = 4x
