The amount of salt is not changing. Water is being added, which changes the volume and the concentration.

How much salt in the tank after 1 hour?
500 pounds of salt, the same as at the beginning.

Water pumped into tank at 3 gallons per minute, which is 3%28gal%2Fmin%29%2A60%28min%2Fhour%29=highlight_green%28180%2A%28gal%2Fhour%29%29.
Amount of Water after 1 Hour: .
The salt concentration is then 500 pounds SALT in 680 gallons of WATER.

Decide what kind of concentration units you want and adjust to fit.
