How much salt could an average person hold? (Ignore safety concerns)
Given equation: 0.3x=y
0.3x meaning mass of water
y mean mass of salt that could be dissolved in the given mass of water
Assuming the average human body has 6075% of water, let us just use 75%
Solve.

If the person weighs 150 lbs, then 150*0.75 = about 112 lbs H2O
0.3*112 = y = ? = lbs salt.
