Question

A city’s population is currently 150,00. If the population doubles every 30 years, what will the population be 60 years from now?

Answer 1

Answer:

60000

Step-by-step explanation:

AFTR 30 YEARS =15000*2=30000

AFTR 60 YEARS=30000*2=60000

Answer 2

First of all, the population is 15,000 NOT 150,00. Do you know why?

After 30 years, 15,000 doubles to become 30,000.

60,000 is twice 30,000.

So, after another 30 years, 30,000 people increases to 60,000.
