a] Population density is given by:
[Total population]/[Area]
PD for city A=44000/55=800 people per sq. mile
PD for city B=48750/65=750 people per sq. mile
Thus city A has a higher population density. 

b] by what percentage it's population density is greater that the other city's
800-750=50 
50/(800+750)=0.0322~3.22%
thus City A has higher population density by 3.22%
