Anna, Ben, and Cindy have M markers together. Anna has A markers, and this is twice as many markers as Ben has. How many markers does Cindy have?

 _____ markers 

Translate into Algebra.

<pre>
Since Anna has A markers, B has {{{A/2}}} markers, according to the condition.

Anna and Ben together have {{{A + A/2}}}  = {{{(3/2)A}}} markers.

So, Cindy has M - {{{(3/2)*A}}} markers.

Is everything clear to you?
