For this case we have the following data:
Drained 3.5 Liters in 4 days. If we want to know the volume of water per day, we make a rule of three:
3.5 Liters -----> 4days
x Liters --------> 1 day
Where x represents the amount of water drained each day.
So, we have to:
Liters per day
So, the average change in water volume each day is: Liters per day
Answer:
Liters per day

Answer.... 32
when a number doubles, it is simply a higher power of 2
so there are 3 butterflies in the beginning, which can also be written as 3 * (2^0) where the 0 is the initial power, since anything to the 0 power is 1 (except for 0)
so the expression would be 3 * (2^n)
after 4 minutes, it would be 3 * (2^4) or 3 * 16 or 48
to find out how many are remaining, we know that she captured 7 of them, so it would be 3 * (2^4) - 7
for question 2, Jeff texts 4 classmates, and then they each text 4 classmates, so that would be 4^2 or 16, but since 2 people do it, it would be
32
