Esmeralda wants to buy some exotic fish with blue speckles and long flowing fins. Mmm...delicious. The person at the fish store told Esmeralda that these particular fish need a lot of water in their tank in order for them to be comfortable: 1 gallon for the tank to start, plus an additional 2 gallons for each fish you throw in there. Esmeralda has a tank that holds 64 gallons of water. How many fish can Esmeralda's tank comfortably hold? Let's assume that Esmeralda does not actually intend to eat these guys, and therefore does have some amount of concern for their comfortability. She's not an animal.
