Two researchers are studying the decline of orangutan populations. in one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. in a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. after how many years will the two populations be the same?

The answer is 3 years.

Step-by-step explanation:

Let the years be denoted by 't' ,when both populations will be same.

1st study says a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year.

Equation becomes:

In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year.

Equation becomes:

Now to solve for 't' we will equal both the equations.

So, t = 3 years.

So, the answer is 3 years.

i'm pretty sure the answer is a. decreases with increase in

the answer on e2020 was d.
