Answer 1

Answer:

Class A : $y= \frac{3x}{5}$

Class B : $y=\frac{1}{2} x$

Step-by-step explanation:

Class A :

Let the amount of Salt in the solution be represented by y as, it is supposed to be the independent variable.

Similarly let the amount of Water in the solution be x

As we are given that for Class A , The ratio of salt  content to water content is  3 to 5

Hence

$\frac{y}{x}=\frac{3}{5}$

Multiplying both sides by x we get

$y= \frac{3x}{5}$

Class B :

Let the amount of Salt in the solution be represented by y as, it is supposed to be the independent variable.

Similarly let the amount of Water in the solution be x

As we are given that for Class A , The ratio of salt  content to water content is  2 to 4

Hence

$\frac{y}{x}=\frac{2}{4}$

multiplying both sides by x we get

$y=\frac{1}{2} x$
