The solution is 20 days, found as follows:
Each of the three friends initially makes 4 bags of dough. After 10 days, each of these bags is split into 4 new bags:
3 friends × 4 bags = 12 bags, and 12 bags × 4 = 48 bags
Then in the following 10 days, 48 bags are again divided into 4 bags each:
48 × 4 = 192 bags
Adding the periods: 10 days + 10 days = 20 days
Therefore, 192 bags are created after 20 days.
The temperature change rate is determined by taking the temperature difference in °F and dividing it by the time measured in minutes. Thus,
rate of change in temperature = -25.5°F / 1.5 min
= -17°F / min
Therefore, the temperature decreases at a rate of -17°F every minute.
