Answer:
4266
Step-by-step explanation:
Okay! let's start with finding what 3% of 5400 birds is
3% is .03 as a decimal. We can find 3% of 5400 by multiplying 5400 by .03
5400×.03= 162
If our rainforest is losing 3% a year, that means we are losing 162 birds a year.
Let's turn it into an equation! x will be the number of years
5400-162x= number of birds left after x years
Now put 7 in for x
5400-(162×7)= 4266 birds
Hope this helps!
