p, how many in the pack.

Andy
p-p%2F4 pieces remain
Alex
p-p%2F4-%28p-p%2F4%29%2F4 pieces remain
Lily
p-p%2F4-%28p-p%2F4%29%2F4-%28p-p%2F4-%28p-p%2F4%29%2F4%29%2F3=36 pieces remain

The rest of the solution is lengthy algebra steps.
You may want to simplify every iteration of paper sharing described before stepping through the "Lily" equation. In fact, you may use the simplification upon each iteration to have a more manageable form of the "Lily" equation to solve.
