asambeis [7]

Answer:

Step-by-step explanation:

If two variables are proportional then

$y\propto x$

$y=kx$ ...(i)

where, k is constant of proportionality.

The given equation is

$s=4c$ ...(ii)

where,

s = number of cups of seltzer.

c = cups of cranberry juice.

On comparing (i) and (ii), we get

Independent variable: $x=c$

Dependent variable: $y=s$

Constant of proportionality: $k=4$

Therefore, the constant of proportionality is 4.
