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

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
