Three friends each create 4 bags of starter bread dough. After ten days, each of those four bags is then divided into four more bags of dough. How many days pass before 192 bags of dough are created
If you add together all of the bags in total, you would have 24 bags (8+8+8), and the 3 friends will have four bags each in total. After another ten days you will have 96 bags of dough (24 x 4). After another ten days there will be 384 bags of dough, so at this point there will be 192 bags of dough available, assuming that the friends continue with the same method.
