tamaranim1 [39]

Answer:

5,175 fish

Step-by-step explanation:

To figure out the total you have to add all the fish together.

Day 1: 750 + 300 + 250 = 1,300 fish were caught on Day 1

Day 2: 720 + 455 + 400 + 50 = 1,625 were caught on Day 2

Day 3: 2,250 were caught on Day 3

Then, add those three numbers

1,300 + 1,625 + 2,250 = 5,175
