the population of bacteria in an experiment has been increasing by 50% each day. If there were 100 bacteria at the beginning of the experiment, predict the number of bacteria in 4 days

506

Step-by-step explanation:

The count is multiplying by 1.5 each day, so after 4 days, it will have multiplied by 1.5^4 = 5.0625

Then the count is predicted to be ...

100·5.0625 ≈ 506.25

The count will be 506 after 4 days.
