Question

Judy is a doctor. She placed a small sample of bacteria in a culture dish and recorded the number of bacteria present each 30 minutes beginning at 12 PM. The table shows Judy's data. If the patten of bacterial growth remains constant, how many bacteria should be present in the culture dish at 2:00 PM?

Answer 1

At 2:00 there will be 38,400 bacteria.

Explanation:

600/150 = 4

2400/600 = 4

So, the bacteria quadruples every half hour.

At 1:30, there will be 2400*4 = 9600.

At 2:00, there will be 9600*4= 38400
