AysviL [449]

Answer:

The population will reach 980,000 in 26 years approximately.

Step-by-step explanation:

Initial Population of city = 490000

Rate of increase in population = 2.75%

We are supposed to find Approximately when will the population reach 980,000

Formula : $N(t)=N_0(1+r)^t$

N(t)= population after t years

$N_0=$ Initial population

t - time

r = rate of interest in decimals

So, $980000=490000(1+\frac{2.75}{100})^t$

t=25.55

So, the population will reach 980,000 in 26 years approximately.
