How many liters of pure water should be mixed with 18 liters of a 12% saline solution to make a saline solution that is 3% salt?

1 answer:

8 0

4 liters because 12% of 18 liters is 2.16 and the goal is 3% so 3% of 18 is 0.54 so you do 2.16/0.54 which equals 4 liters of water

Given

The attached graph

Required

Calculate the constant of proportionality.

Represent the required constant with k.

Such that:

$k = \dfrac{y}{x}$

Pick any two corresponding values of x and y

$(x,y) = (1,40)$

This means that:

$x = 1\ and\ y = 40$

$k = \dfrac{y}{x}$ becomes

$k = \frac{40}{1}$

$k = 40$
