Chef Charming and his mother sell cheese steak sandwiches at their food truck. They use fresh onions, and cook them slowly to caramelize them before putting them on their sandwiches.  Charming found a pre-cooked onion that was $10.0 per pound AP$, with 100% Yield. He wants to save money but isn’t sure if that is a better deal than cooking the fresh onions himself.  He currently pays an AP$ of $2.55 per pound for fresh onions, but his yield is 50% after peeling and cooking the onions.  What is the EP$ for the fresh onions, after caramelizing?
