Question

A town of population 2000 doubles every five years. How long will it take the town to
reach 20,000?

A- 15.3 years
B- 16.6 years
C- 18.2 years
D- 10 Years

Answer 1

Step-by-step explanation:

Year 1 = 2000

Year 5 = 4000

Year 10 = 8000

Year 15 = 16000

Year 20 = 32000

5 years = 16000

1 year = 16000/5

1 year = 3200

16000 (15yrs) + 3200 (1yr) = 19200

6/10 × 3200 = 0912

16000 (15yrs) + 3200 (1yr) + 912 (.6yr) = 20112

Possible ans = B
