Answer:
Approximately 284 Fish.
Explanation:
To estimate the number of fish the dolphins ate, you would subtract the number of fish left after feeding from the initial number of fish.
Initial number of fish: 553
Number of fish left after feeding: 269
Fish eaten by the dolphins = Initial number of fish - Number of fish left after feeding
Fish eaten by the dolphins = 553 - 269
Fish eaten by the dolphins = 284
Therefore, based on the given information, the dolphins ate approximately 284 fish.
