A certain forest covers an area of 3100. Suppose that each year this area decreases by 4.75% . What will the area be after 7 yea
e-lub [12.9K]

Answer:

Step-by-step explanation:

This can be represented as exponential decreasing function.

   y = a(1 - r)t

       a = starting amount

       r = rate

       t = years

   y = 1600(1 - .0725)15

     = 1600(.9275)15

     = 1600(.32337673)

     = 517.40

In 15 years,  the forest will shrink in size to 517.40 km2
