Answer:
a - city's population at year 0
r - rate of population increase
t - number of years
In four years, the population will be 65,558
Step-by-step explanation:
y = a(1+r)^t
for year 1
y = 63,000(1+0.01)^1
y = 63,630
for year 2
y = 63,000(1+0.01)^2
y = 64,266
for year 3
y = 63,000(1+0.01)^3
y = 64,909
for year 4
y = 63,000(1+0.01)^4
y = 65,558
