Answer:
60000
Step-by-step explanation:
AFTR 30 YEARS =15000*2=30000
AFTR 60 YEARS=30000*2=60000
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.
