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!
