Answer:

The salt is in the water be 3 lb.

Explanation:

Formula


Percentage = (Part\ value* 100)/(Total\ value)

As given

Twenty pounds of a salt-water solution contains fifteen percent salt.

Let us assume that the salt is in the water be x.

Percentage = 15%

Total value = 20 pounds

Put in the formula


15= (x* 100)/(20)


x = (15* 20)/(100)


x = (300)/(100)

x = 3 pounds

or

x = 3 lb

Therefore the salt is in the water be 3 lb.
