Suppose that the number of bacteria in a colony triples every hour.
a.
If 100 bacteria are used to begin a new colony, how many bacteria will be in the
colony after 10 hours?
b. Set up a recurrence relation for the number of bacteria after n hours.
A factory makes custom sports cars at an increasing rate. In the first
