How Much Does a 100x100 Five Guys Cheeseburger Cost?

The Situation:

Five Guys Burgers and Fries ordinarily sells hamburgers, cheeseburgers (two beef patties and two slices of cheese) and little hamburgers and cheeseburgers (a single beef patty and a single slice of cheese). While they don’t advertise it, they have a secret menu which includes a burger where you can order as many extra beef patties and cheese slices as you like. The prices and nutrition information are not listed though. The most common orders are 3x3’s (read as “three by three”) and 4x4’s (read as “four by four) that contain three and four layers of beef and cheese, respectively. However some people have ordered 20x20’s and even a 100x100 (pictured below).
