It is reported that the grizzly bear population has increased by 140%. There are now 600 grizzly bears living in the wild. How many Grizzly bears were there in 1975?

a) 250
b) 375
c) 415
d) 240

Answer 1

To determine the number of grizzly bears in 1975, we need to set up an equation using the percentage increase and solve for the original population.

Step-by-step explanation:

To find the number of grizzly bears in 1975, we need to determine the original population before the reported increase of 140%. We can set up an equation using the percentage increase:

Original population + (Original population x 140%) = 600

Simplifying the equation:

1 + 1.4 = 600

2.4 = 600

Original population = 600 / 2.4 = 250

Therefore, there were 250 grizzly bears in 1975.
