Answer 1

Answer:

60800

Step-by-step explanation:

2 years after population

= 64000- (25/1000 ×64000×2)

= 64000 -3200

= 60800

Answer 2

amount = principle (1 - r/100)raise to the power n

amount = 64000 ( 1 - 25/1000 )²

amount = 64000 × 975/1000 × 975/1000

amount = 60840000000/1000000

amount = 60840

therefore, the population of a town after 2 years = 60840
