Bacteria begins to grow on the water's surface in a non-operational swimming pool on September 20. The bacteria grows and covers
the water's
surface in such a way that the area covered with bacteria doubles every day. If it continues to grow in this way, the water's surface will be
entirely covered with bacteria on September 28.
When will a quarter of the water's surface be covered?
O A.
The water's surface will be covered a quarter of the way on September 24.
B.
The water's surface will be covered a quarter of the way on September 26.
C.
The water's surface will be covered a quarter of the way on September 27.
OD. The water's surface will be covered a quarter of the way on September 25.

Ways to divide it into period of seconds
What this question implies is to determine the total number of factors of 86400
To start with, we determine the prime factorization of 86400
To do this, we continually divide 86400 by 2; when it can not be further divided, we divide by 3, then 7, then 11...
This implies that:
The number of factors d is the solved by:
Where
By comparison:
So:
<em>Hence, there are 96 total ways</em>
