Question

A colony of 900,000 bacteria doubles

in size every 85 hours. What will the
population be 255 hours from now?
bacteria

Answer 1

2,700,000

Explanation:

is the answer because 255÷85 is 3 then times 3 by 900,000 then you get 2,700,000.

Answer 2

255 hours / 85 hours = 3.

This means that the bacteria will double in size 3 times.

900,000 × 2 = 1,800,000

1,800,000 × 2 = 3,600,000

3,600,000 × 2 = 7,200,000

After 255 hours, the colony of bacteria will be 7,200,000
