Complete question :

There are tiger barbs in a 30-gallon aquarium and giant danios in a 20-gallon aquarium

Use the rule to solve this problem. The rule for the number of fish in an aquarium is to allow 1 gallon of water for each inch of length.

Giant Danio=5 inch length

Tiger barb=3 inch length

What is the correct numerical expression that represents the greatest total number of fish that could be in both aquariums?

14

Step-by-step explanation:

Given that :

Tiger barbs = 30 gallon aquarium

Giant danios = 20 gallon aquarium

Greatest number of fish that coild be in both aquarium :

Tiger barb = volume / length

Tiger barb = 30 / 3 = 10 fishes

Giant danios = volume / length

Giant danios = 20 /5 = 4 fishes

Hence, the greatest total number of fishes in both aquarium is :

Number in Tiger barb + number in giant danios

10 + 4 = 14
