Three friends each created 4 bags of dough. after 10 days, each of those 4 bags is then divided into 4 more bags of dough. how many days has pass before 192 bags of dough are created?

We start with 12 and then quadruple every 10 days
12*(4)^x = 192
4^x = 192/12 = 16
log4(16) = x
x = 2
2 * 10 = 20 days
