You can put this solution on YOUR website! c, age for Charisse
c+2, age for Kimberley
 -----------solve!
This may give non-whole numbers, so not certain if problem is written correctly.
Further, if you solve for c, you find approximately c=4.567764, but this does not come close enough a whole number of time units.

List out the ways to factor 30
1*30
2*15
3*10
5*6
We focus on the positive factors only.
Unfortunately, none of these pairs are spaced 2 units apart.
If Kimberly was say 1 year older than her sister Charisse, then Kimberly would be 6 and Charisse would be 5.
But there are no integer solutions for this current problem where Kimberly is 2 years older than her sister.
