Answer 1

Answer:

470250

Step-by-step explanation:

Initial population: 450000

Increase%: 10

450000 * 10/100 = 45000

450000-45000=495000

495000*5/100=24750

495000-24750=470250

Answer 2

Answer:

given: r1 = 10% ∧ r2 = 5% ∨, P = 450000

to find the population after 2 years

Step-by-step explanation:

formula used: A = P(1 + r1/100)¹ × (1 - r2/100)¹

=> A = 450000(1 + 10/100) (1 - 5/100)

=> A = 450000(11/10)(19/20)

=> A = (450000×11×19) / 200

=> A = 4,70,250

population at the end of 2 years is 4,70,250
