Scientists studied the population of a species of bat in some caves in Missouri from
1983 to 2003. In 1983, there were 141,200 bats living in the caves. That number
decreased by about 11% annually until 2003.
How many bats were there in 2000?
O A) 13,729 bats
OB) 19,474 bats
OC) 58,210 bats
OD) 62,455 bats

Answer 1

Answer:

B) 19474 bats

Step-by-step explanation:

Initial population of bats = 141200

Decrease rate = 11% annually

Time passed until the year 2000 = 2000 -1983= 17 years

Bats population in 2000:

• 141200 * ((100-11)/100)^17 ≈ 19474 bats

Correct answers choice is: B) 19474 bats
