Answer:
Approximately after 15 years the population will reach 620,000
Explanation:
Population at start : 310,000
Rate by which the population is increasing: 4.5%
Population after n years is calculated under the next equation:
P=Po(1+r)∧n
620,000=310,000(1+ 0.045)∧n
2= (1+ 0.045)∧n
log(2)=nlog (1+ 0.045)
log(2)=nlog (1.045)
log(2)/log(1.045)=n
n= 15
