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.

Hey Kat! :)
Glad to see you on Brainly.
Look below and watch how we solve this problem.
Ask any questions if you need it! I'll respond when you need it!
This is a bit of a hard, one. So please ask questions.
------
Please use the rule a/b x c/d = ac/bd while solving.
After using that equation, it should look like this:
2 x -5 x -3 / 7 x -8
Simplify 2 x -5 to -10.
Now, it should look like -10 x -3 / 7 x -8
30/7 x -8
30/-56
- 30/56 (the negative is front of the WHOLE equation.)
-15/28 is our final answer.
Answer:
The formula for surface area of a right triangle is A = b∙h2 where b is base and h is height.
