the population of masterton was 23 000 in 2012. Assume that Masterton population increases at a rate of 2% per year. Write an equation to model the population of masterton (y) based on number of years since 2012(x)

Verified Answer :

So, let's first focus on the first year:

the population then would be: 23000 (100+2)%

100% is the old population the 2% is the incease, so in total it's 102%, or 1.02 - the same number written differently.

So it will be 230001.02

After two years it will be 230001.021.02, and so on

so after x years it will be:

y=23000*\(1.02^{z}\)
