Answer:

Step-by-step explanation:
We can use the exponential growth formula:
y = a(1+r)ˣ
where
y = amount after x time
a = initial amount
r = growth rate as a decimal fraction
x = number of years
Data:
a = 170 000
r = 0.04
Calculations:

The figure below also shows that the population will grow to about 272 000 in 12 yr.
