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.
