In 20xo, the city had a population of 120,000, suburb x had a population of 80,000, and suburb by had a population of 50,000. Assuming that the population in the metropolitan area remains constant at 250,000 people.

Solution:

if data in table are shift of population in proportion of total population (250000 people), then:

for 20X2 year:

city; $120000+250000(-0.15+0.01)=85000$ people

suburb x: $80000+250000(0.07-0.04)=87500$ people

suburb y: $50000+250000(0.08+0.03)=77500$ people
