I've got 1400 Lemonade Stands and i got 79 duodecillon profit per second. If we suppose that one Lemonade Stand can sell one lemonade the second that would be 56 undecillon dolars for one lemonade. Wow, that's much more that I earn in a whole month.

I´m stuck on lvl 11. I know it´s a scuare but i don´t know how to type it on my keyboard :(
