Okay, here we have this:

Considering the provided information, we are going to calculate the requested value, so we obtain the following:

Accordingly, since the amount of salt remains the same, then we have the following equality, where x represents the amount of water that must be added:

0.4(85)=0.17(x+85)

Let's solve for x:

34=0.17x+14.45

0.17x=34-14.45

0.17x=19.55

x=19.55/0.17

x=115

Finally we obtain that must be added 115 ounces of water to make a solution that is 17% salt.
