Question

Jason enjoys watching the squirrels in his neighborhood park. They eat the red oak acorns. After the city removed 4 diseased red oak trees, the population of squirrels decreased from 105 to 98 in one year. If the population continues to decline at the same rate, how many squirrels will live in the park in 15 years? First, calculate the rate of decay by subtracting the two populations and dividing the difference by the initial population. Then, use the formula A=a0ekt

a. 0 squirrels
b. 95 squirrels
c 81 squirrels
d 34 squirrels ​

Answer 1

34 Squirrels

Explanation:

7\ 105 ~0.07

A=Aoe^kt

A=98e^(-0.07•15)

A=98e^-.05

A=34.3~ 34 Squirrels

Answer 2

0 squirrels

Explanation:

If you subtract 98 from 105 then you get 7. That means that 7 squirrels will be lost per year. If you then multiply 7 by 15 (15 is the amount of years) then you get 105 and since there were 105 to start off with, there will be no squirrels left after 15 years.
