The city of toronto’s population rose from 2,000,000 to 4,500,000 in the last twenty years of the twentieth

century. what was the annual average percentage increase in population for that period?

 125,000

Step-by-step explanation:

Initial Population                                                  = 2,000,000

Population increase                                             = 4,500,000

Increase in Population                                        = 4,500,000 - 2,000,000

                                                                              = 2,500,000

Duration of  Population increase ( Range)          = 20 years

Therefore, the annual average % increase         = 2,500,000/20

                                                                              = 125,000

x/7.50 = 15

x= 7.50 / 15 divide
