Question

If the number of bacteria in a colony doubles every 45 hours and there is currently a population of 500,000 bacteria, what will the population be 180 hours from now?

Answer 1

8,000,000

Explanation:

180 divided by 45 equals 4.

500,000 times 2 equals 1,000,000

1,000,000 times 2 equals 2,000,000

2,000,000 times 2 equals 4,000,000

4,000,000 times 2 equals 8,000,000
