Bacteria colonies can triple in size every 4 days. if you start with 40 bacteria microorganisms, how large would the colony be after 20 days?

The size of the bacteria colony after 20 days = 9720

Step-by-step explanation:

The number of bacteria micro organism at the starting = 40

Now, The size of the bacteria colonies triple in size every 4 days

and we need to find the size of the bacteria colony after 20 days.

So, after 4 days the size of bacteria colony = 40 × 3

                                                                        = 120

After 8 days, The size of the bacteria colony = 120 × 3

                                                                           = 360

After 12 days, The size of the bacteria colony = 360 × 3

                                                                            = 1080

After 16 days, The size of the bacteria colony = 1080 × 3

                                                                            = 3240

After 20 days, The size of the bacteria colony = 3240 × 3

                                                                                = 9720

Therefore, The size of the bacteria colony after 20 days = 9720

For the first one the answer is: 17%

And for the second one the answer is 26%
