If toilet paper becomes the new form of currency, we gotta figure out this math

2.25 regulars in a double plus, 2 double plus in a mega plus

The mega plus is 1 for every 4.5 regular rolls. Double plus is 1 for every 2.25 or 2.26 or 2.27 regular rolls so this one is questionable. The plain mega is 1 for every 4 regular roll.
