Question

A population of rabbits is increasing continuously at a rate of 20% each year. If there were 25 rabbits in the year 2012, how many rabbits will there be in the year 2017? Round your answer up to the nearest whole rabbit.

Answer 1

Answer:

62

Step-by-step explanation:

20% as a decimal is 0.2

For each year get the amount of increase by multiplying the number of rabbits by 0.2

Rabbits in 2013:

25 x 0.2 = 5

25 + 5 = 30 rabbits

Rabbits in 2014:

30 x 0.2 = 6

30 + 6 = 36 rabbits

Rabbits in 2015:

36 x 0.2 = 7.2

36 + 7.2 = 43.2

Rabbits in 2016:

43.2 x 0.2 = 8.64

43.2 + 8.64 = 51.84

Rabbits in 2017:

51.84 x 0.2 = 10.368

51.84 + 10.368 = 62.208

= 62 rabbits
