The population is the amount of people, so there would be $$1.3*10^4$$ people. Which is the same as 130000.

anonymous · Answer

Should I divide  or subtract since its asking how many "more" people are there in algeville ?

skullpatrol · Answer

subtract to find the difference between the two populations

anonymous · Answer

@skullpatrol since its subtracting scientific notation it would be 5.6×10³ - 1.3×10⁴ ?

skullpatrol · Answer

yes

anonymous · Answer

You should subtract 1.3×10⁴-5.6×10³

skullpatrol · Answer

but change the numbers so they are easier to work with
