Question

A culture started with 3,000 bacteria. After 8 hours, it grew to 3,300 bacteria. Predict how many bacteria will be present after 12 hours.

Answer 1

3,450 bacteria

Explanation:

3,300 - 3,000 = 300

8 hrs = 300 bacteria increase

300 / 8 = 37.5

Every hr = 37.5 bacteria increase

37.5 x 12 = 450

Total = 3,000 + 450 = 3,450
