Since $14 is the price after a 30% discount then $14 is 70% of the original price.

$14/70=x/100 (100% would be the original price)

1400=70x or 1400/70 = $20!

You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!

for a different punch recipe, the equation,s=4c represents the number of cups of seltzer,s, that you need for,c, cups of cranber

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.
