210000/178500 = 1.17647, and so we need 1.021^n = 1.17647, and ln(1.17647)/ln(1.021) = n = 7.8, so about 8 years.

multiply the population (178,500) by 2.1% or (.021) and add the answer to your population (178,500)

so in about 7 years, 10 months the population will be 210,000

“Per annum” is latin for “per year”, or in this case, annually. Therefore, multiply 178,500 by 2.1% (or .021) and then add the result to 178500. This will yield the increase in the population.

Best of luck!

The equation to figure this out would be

178500+.021X=210000

First subtract 178500 from 210000

210000-178500=31500

so you get

.021X=31500

Then divide 31500 by .021

so X=1500000
