Question

The population of town a increases by 5% every year. its current population is 700,000. town b, which currently has 550,000 residents, increases by 6.5% each year. if the growth of each town continues to increase at the current rate, what is the difference in the populations of town

Answer 1

A) Town A has 139,849 more residents than Town B is the correct answer

Answer 2

The difference in population is 150750

Step-by-step explanation:

current populations :

Town A = 700000

Town B = 550000

Town A = 5% increase led to 700000

Town B = 6.5% increase led to 550000

therefore original population before increase is

Town A = 700000 - ( 5% of 700000 )

= 700000 - ( 35000 )

= 665000

Town B = 550000 - ( 6.5% of 550000 )

= 550000 - ( 35750 )

= 514250

hence the difference in population is the difference in original population which is: 665000 - 514250 = 150750
