You receive an email asking you to forward it to four other people to ensure prosperity. Assuming the chain isn't broken , how many emails will have been received and sent after 8 email generations including yours?
A.5,460 emails
B.21,844 emails
C.65,537 emails
D. 5,461 emails
In this problem we have an exponential function of the form
y=a(1+r)^x
where
a=1 -----> initial value
r=300%-----> r=3
so
y=(1)(1+3)^x
where
y is the number of emails
x is the number of generations
For x=8
substitute
y=4^8
y=65,536
including yours
65,536+1=65,537
the answer is the option C
