Question 785994: You are thinking of purchasing an aquarium for your parents. You need to know how many fish to purchase for an aquarium. The rule of thumb is to purchase "as many fish that measure 3 inches, or 3 fish-inches, for each 2 gallons of water in an aquarium."
a) define variables for the quantities that are changing in this problem situation.
We came up with 3 fish/2gallons of water equals 1 fish/2 gallons of water. I don't know if this is correct.
b) write an equation for fish-inches based on the gallons of water.
we came up with: 3/2 = x/10
30/2x
x = 15 one inch fish per 10 gallons of water
or 5 three inch fish
Is that correct?
c) Use your equation to answer each of the following questions:
If an aquarium holds 10 gallons of water, how many fish inches should you purchase? Is 15 one inch fish or 5 three inch fish correct?
d) If you want to purchase a 5 - inch fish, two 2inch fish, and three 3 inch fish, how many gallons of water should the aquarium hold? Show your work. I have no clue how to do this.
