15 people received an email and sent it to 3 different friends each, who in turn sent it to 2 new people. what percent of the total number of people who received the email are in the original 15 people?

Step 1: Multiply 15 by 3, which equals 45.
Step 2: Multiply 45 by 2, which gives you 90.
Step 3: Add everything up. 15 + 90 + 45 is 150
Step 4: Find the percent of 15 people in a group of 150 people by diving 150 by 15.

150 / 15 = 10.
