Question

. Jill decides to move her fish from a 20 gallon aquarium to a 50 gallon aquarium. She added 3 tablespoons of salt to her old aquarium. If she wishes to maintain to same salinity level, how many tablespoons should she add to her new aquarium

Answer 1

7.5 tablespoons of salt

Step-by-step explanation:

The old aquarium had 20 gallons of water while the new aquarium had 50 gallons of water.

If 20 gallons of water required 3 tablespoons of salt

50 gallons of water will require: 50 x 3/20 = 7.5 tablespoons of salt

Hence, 7.5 tablespoons of salt should be added to her new aquarium.
