Question

It is reported that the grizzly bear population has increased by 140% since 1975.

there are now 600 grizzly bears living in the wild.
how many grizzly bears were there living in 1975?

Answer 1

250

Explanation:

If we let p represent the 1975 population, we have ...

p + 140%×p = 600

p(1 +1.40) = 600

p = 600/2.4 = 250

There were 250 grizzly bears living in the wild in 1975.
