A scientist collects data on bacteria in a petri dish. She finds that the number of bacteria grows exponentially and can be modeled using the equation Y = 16 x 1.8^x, where x is the number of hours after she sets up the experiment and y is the number of bacteria in the dish. Complete the sentences to describe the model.
The scientist started with around __ bacteria in the petri dish.
