Answer 2

In this question, it is given that

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.

And we have to find number of bacterias on day *.

For that we use the following formula

`N(t) =N_(0) (1 +r)^t`

`N(0)= 420, r = 0.18 , and \ t = 8days`

Substituting these values in the formula, we will get

`N(8)= 420(1+0.18)^8 \\ N(8)=1579`

THerefore on day 8, number of bacterias are 1579.
