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?
Answer:
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
