[2 marks] Situation Equation A bacteria colony has a population of 400 at 8:00am. The population triples every 16 hours. Let P(t) represent the population of the bacteria colony, in t hours after 8:00am The value of a $40,000 truck depreciates at 30% per year for tax purposes. Let V(t) represent the value of the truck after t years 2. Complete the table.
