Answer:
C. 1750
Explanation:
Okie dokie, so we know that there are 350 fish in 200 square feet, but there are 1000 square feet in the pond.
We first have to figure out how many times 200 goes into 1000.
This is 5, which means we can approximate there are 5 times as many fish.
So all we have to do now is multiply the 350 trout by 5.
This gives us 1,750 trout.
I hope this helps :)
