Answer: Option 'B' is correct.
Explanation:
Since we have given that
Number of lemons used is denoted by 'y'.
Number of glasses of lemonade is denoted by 'x'.
As we can observe that ,
[tex]\frac{6}{24}=\frac{8}{32}=\frac{7}{28}=\frac{2}{8}=\frac{4}{16}=\frac{1}{4}\\\\\text{So, we can write it as :}\\\\\frac{x}{y}=\frac{1}{4}\\\\\text{ By cross multiplication}\\\\y=4x[/tex]
So, if write it in the form y=kx,
It will be y=4x.
Hence, Option 'B' is correct.
