Question

There is a population of 1,000 bacteria in a colony. If the number of bacteria doubles every 21 hours, what will the population be 63 hours from now?

Answer 1

3000

Explanation:

21 hours x 3 = 63 hours

if the bacteria doubles every 21 hours, in 63 hours it would have doubled three times. 1,000 bacteria x 3 = 3,000 bacteria

Answer 2

6,000

Explanation:

1,000*2=2,000

63/21=3

2,000*3=6,000
