Question

Come up with 2 different questions and corresponding equations for this context:
"A vampire enters a town. He looks around for about an hour, and then chooses someone to bite. The person he bit is now also a vampire. Both of them take an hour to choose new victims, and then they each bite someone. All the vampires continue choosing victims in the same way."
Thank you so much

Answer 1

There are MANY examples:

You could make x = time in hours and y = number of vampires:

y = $2^{x-1}$

OR you could make x = time in hours and y = number of victims:

y = $2^{x-1}-1$

You could make y = number of vampires and x = time in hours:

$log_{2}{(x)}+1 = y$

etc.
