Calculate the population of 217 bison at the end of 2 years if it decreases at a rate of 7.5% per year. _____ bison

Answer :

7.5% of 217 = 16.275

At end of 1 year bisons = 217 - 16.275 = 200.725

7.5% of 200.725 = 15.054375

At end of 2 years bisons = 200.725 - 15.054375 = 185.670625 (Rounding that to the tens)

=186

Bison = Pe^-kt
(P is the initial amount of bison, which is 217)
(Also, make 7.5% negative to represenr population decay, not growth. Next, convert 7.5% to decimal form: 7.5/100 = .075)

Solve:

1. Bison = 217e^(-.075)(2)
2. Bison = 186.77 bison,
Since we can’t have .77 of a bison XD) and depending on rounding, you can have 186 or 187 bison!

Good luck!
