Question

The population of Bridgetown triples every decade. If the population

in the year 2000 was 25,000, how many people will be living in Bridgetown
in 2030?

Answer 1

Between 2000 and 2030 three decades will have gone by, which means the population will triple three times.


`2000-25,000 \\ 2010-25,000*3=75,000 \\ 2020-75,000*3=225,000 \\ 2030-225,000*3=675,000`

Therefore, the population of Bridgetown will be 675,000 people in 2030.
