Answer:
The penquins had more fish.
Number of fish polar bears and penguins had combined is 5,520.
Step-by-step explanation:
The polar bears had 2,208 fish (48 piles times 46 fish).
The penquins had 3,312 fish (144 piles [48 times 3] times 23 fish [46 divided by 2]).
2208 fish plus 3312 fish equals 5,520 fish.
