Any more good news?
Yeah, hockey - I mean the "stick-fight" - is almost over. Sanity will prevail again over the air-land (not really with upcoming election) .....
Hello again, dave7!
I saw another interpretation . . . but it didn't help.
Suppose "had" refers to his original amounts?
He began with: \(\displaystyle D\) dollars and \(\displaystyle C\) cents.
Later he had: \(\displaystyle \frac{D}{3}\) dollars and \(\displaystyle \frac{C}{3}\) cents.
We are told: .\(\displaystyle \begin{Bmatrix}\frac{D}{3} &=& C \\ \frac{C}{3} &=& 3D \end{Bmatrix}\) . . . . and these are contradictory.
