Answer:
C) 78,200
Step-by-step explanation:
If p represents the population in 2010, then the population in 2012 is ...
p + 0.30p = 1.30p
and the population in 2014 is ...
(1.30p) + 0.20(1.30p) = (1.30p)(1.20) = 1.56p
This is the same population as in 2015, so we have ...
1.56p = 122,000
p = 122,000/1.56 ≈ 78,200 . . . . rounded to hundreds
In 2010, the population of Maple Mall was about 78,200.
