How much water must be evaporated from 20 gallons of a 10% salt solution in order to obtain a 20% salt solution?

8 gallons have to be evaporated to have a 20% salt solution.

hope this helped :)

Step-by-step explanation:

.10*20=2 gallons of salt.

That leaves 18 gallons of water.

.2x=2

x=2/.2

x=10 gallons after evaporation.

18-10=8

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:
