Chain emails are emails with a message suggesting you will have good luck if you forward the email on to others.
suppose a student started a chain email by sending the message to 3 friends and asking those friends to each send the
same email to 3 more friends exactly 1 day after receiving it.
b. which day is the first day that the number of people receiving the email exceeds 100?

b.

starts with student-day one

3*3=9-day two

9*3=27-day three

27*3=81-day four

81*3= over 100- day five

it's day 5 unless you count the first student sending the message as day 0, if so then your answer is day 4

x + 4/7
