Problema Solution

suppose a city with population 400,000 has been growing at a rate of 2% per year. If this rate continues, find the population of this city in 16 years.

Answer provided by our tutors

start population is 400,000


after 1 year: 400,000 + 0.02*400,000 = 400000*1.02


after 2 years: 400,000*(1.02)^2


after x years: 400,000*(1.02)^x


after 16 years: 400,000*(1.02)^16 = 549,114
