We have 500 grams of a 10% salt solution. How many grams of water must be added to dulite the solution to form a 4% solution. Show work

Hmm, one way is this

there's 500 times 0.10 or 50 grams of salt in the water

if we want to make 50 grams=4% of everything, how much water do we need to add

50=4% of all

50=0.04 of all

divide both sides by 0.04

1250=all

so

500+what=1250

minus 500 both sides

what=750

750 grams of water

500x. 04 = 200 grams?

Good Luck!
