Question

* There are 1,000 of an endangered species of bird left. If the population drops by 50% each year, how many years until there are only 1% of the current total left? ( round to a whole number)

Answer 1

1,000 * 0.01 = 10

Year 1 = 500
2 = 250
3 = 125
4 = 62
5 = 31
6 = 16
7 = 8

Answer 2

7 is the correct answer but I feel there needs to be reasoning to it so maybe next time you could give an explanation
