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?

She should add 7.5 tablespoons of salt. The fish gonna be saltyy. YOU'RE WELCOME :)

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
