    500x. 04 = 200 grams?

    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
