we already know that in 20 years the population changed from 100,000 to 150,000

so we do this

150,000 / 100,000 = 1.5

1.5 is also the same as 150%

or 7.5% increase per year

so all we do is

150,000 * 1.5 = 225,000

we dont need to change anything as it is the same amount of years
