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 befoe 192 bags of dough are created?

55 days

Step-by-step explanation:

Number of bags of dough is 192

You have to calculate the number of days.

After 10 days, 4 bags are divided into 4 more bags: 4 + 4 = 8

After 20 days: 8 + 8 = 16

After 30 days: 16 + 16 = 32

After 40 days: 32 + 32 = 64

After 50 days: 64 + 64 = 128

After 55 days: 128 + 64 = 192 (5 days will be considered since it is doubled in 10 days and this time it is divided into half the amount)

Therefore, 55 days pass before 192 bags of dough are created.
