Question 1106166
<br>
If a formal algebraic solution is not required, try common sense, a little logical reasoning, and some simple mental arithmetic.<br>
(1) Julie's age in 2011 is the square of her age in 2005, 6 years earlier.
(2) What number is there for which the difference between the number and the square of the number is 6?
(3) Answer: 3.  3 squared is 9, which is 6 more than 3.
(4) So Julie's age in 2005 was 3 and in 2011 it was 9.
(5) So in 2008 her age was 6.
