Answer:
t = 13.1576 years
Step-by-step explanation:
The situation can be modeled as
P = Po.(1-r)^t
Where
t is the years transcurred
Po is the initial amount
r is the rate of change
Po = 40000
r = 10% equivalent to 0.1
Now
A quarter of the original amount
(1/4)*Po = Po.(1-r)^t
(1/4) = (0.9)^t
t = 13.1576

Step-by-step explanation:
Well, this is a stem and leaf problem.
The numbers are 20, 28, 29, 29, 31, 32, 36, 41, and 42.
In order to solve for the mean, we find the average and we add the numbers together and divide by 9(there are 9 numbers).
The mean is 32.
The median is the middle number, or 31.
