Calculate population increase 2011: Calculate the population increase for the year 2011.The population in 2010 was 12,000 and it increased by 5% in 2011.To find the increase, calculate 5% of 12,000.Increase =1005×12,000Increase =0.05×12,000Increase =600
Calculate population 2011: Calculate the population for the year 2011.Add the increase from Step 1 to the population of 2010.Population in 2011 = Population in 2010 + IncreasePopulation in 2011 = 12,000+600Population in 2011 = 12,600
Calculate population increase 2012: Calculate the population increase for the year 2012.The population in 2011 was 12,600 and it increased by 7% in 2012.To find the increase, calculate 7% of 12,600.Increase =1007×12,600Increase =0.07×12,600Increase =882
Calculate total population increase: Calculate the total population increase over the 2-year period.Add the increases from Step 1 and Step 3.Total increase = Increase in 2011 + Increase in 2012Total increase = 600+882Total increase = 1482
