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