White Board Markers
Pro Problems > Math > Algebra > Equations > Word Problems > LinearWhite Board Markers
I have a problem with dry erase markers disappearing from my classroom. A third of my markers were stolen by a student, and then one of my co-workers "borrowed" four markers. After that I realized that half of the remaining markers didn't work, so I threw them away.
In the end, I just had two markers left.
How many did I start with?
