-2
Step-by-step explanation:
Using the formula
P₁V₁ = P₂V₂ (where P is percentage and V is volume in pounds)
∴

(where x is the unknown volume being found)

x = 25
∴ In order for only 12 % of salt to be percent you need to have 25 pounds of water but since you already have 20 pounds of water and 15 % salt, you only need to find how much more pounds of water to add which is 5 (25 - 20 = 5)
