You are thinking of purchasing an aquarium. you contact the owner of
an aquarium store. you need to know how many fish to purchase for
an aquarium, but first you must determine how big the aquarium will
be. the owner of the aquarium store tells you his rule of thumb is to
purchase “a total length of fish of 3 inches for each 2 gallons of water
in the aquarium.”
1. how many gallons of water would you need if you had a
4-inch fish and a 2-inch fish? draw a diagram to explain
your reasoning.
2. define variables for the quantities that are changing in this
problem situation.
