Two of the most dangerous animals in the enchanted forest are snakes and bears. The population of bears began with 100 bears in
SOVA2 [1]

Answer:

Yes

IT WILL TAKE 8 YEARS.

Step-by-step explanation:

Bear starting population = 100

Bear population rate = 4 per year

Snake starting population = 1

Snake population rate = doubles every year

Bear population model:

y = 4x+100

Where y = new bear population

x = number of years after year 2000

Snake population model :

y = 2^x

Where y = new snake population

x = number of years after year 2000

THE POPULATION OF SNAKES WILL CATCH UP WITH THAT OF BEARS BECAUSE AFTER 7 YEARS THE POPULATION WILL BE EVEN.

After 7 years :

Bear population :

y = 4x + 100

y = 4(7) + 100 = 128

y = 128

Snake population :

y = 2^x

y = 2^7

y = 128

Using random guess in the both models :

After 8 years :

Bear population :

y = 4x + 100

y = 4(8) + 100 = 132

y = 132

Snake population :

y = 2^x

y = 2^8

y = 256
