Thread: Have I concluded a good formula

The population of animal in a country Park increases in number by 11 percent each year. A survey counted the number of animal in the park at the start of a particular year. If the number of animals counted was K, is the following formula connecting the current number, N, with time t in years since the initial count a correct formula to use?

N = K x 11 x t

N = K x 11 x t

1. Your formula is not correct.

2. In the beginning, that means t = 0, you have K animals.

After one year, t = 1, you have

Next year, t = 2, you have

After x years, t = x, you have

N = K x 11 x t

At the start .
Then after one year
After two years
So after t years

Thanks for your help, I read it as; N(x) = K x 1.11^x
