Final answer:

The number of birds in a forest is decreasing by 3% every year. Starting with 5400 birds, after 7 years there will be approximately 4460 birds in the forest.

Step-by-step explanation:

To calculate the number of birds in 7 years, we need to find the number of birds after each year of decreasing by 3%. Starting from 5400 birds, we can find the number of birds in each year by multiplying the previous year's count by 0.97 (100% - 3%).

After 1 year: 5400 * 0.97 = 5238 birds

After 2 years: 5238 * 0.97 = 5080 birds

Continuing this pattern for 7 years, we find that there will be approximately 4460 birds in the forest.
