Answer:
I think so yeah. not sure though
The original 15 people are 10% of the total number of people who received the mail.
Step-by-step explanation:
Given,
Number of people who received mail = 15
Mail further sent to 3 more friends;
Number of people who received mail from 15 people = 15*3 = 45 people
Number of people who received mail from 45 people = 45*2 = 90 people
Total number of people = 15+45+90 = 150 people
Now,
Percent of original people = 
Percent of original people = 
The original 15 people are 10% of the total number of people who received the mail.

Using the formula
A = Pe^kt
Where A is the ending amount of population, P is the population k is a constant and 't' is time.
A = 0.39, t= 12 and p= 0.29
0.39= 0.29e^12k
1.34 = e^12k
ln1.34 = 12k
ln1.34/12 = k
K= 0.02
No the graph does not support his claim as k should be equal to 0.5
