The count of bacteria in a culture grows by 10% in the first hour, decrease by8 % in the second hour and again increases by 12% in the third hour. If the count of bacteria in the sample is 13125000, what will be the count of bacteria after 3 hours?

Explanation

To solve the problem step by step, we will calculate the count of bacteria after each hour based on the given percentage increases and decreases.

### Step 1: Initial Count of Bacteria
The initial count of bacteria is given as:
\[ P = 13125000 \]

### Step 2: Calculate Count After First Hour
The bacteria count increases by 10% in the first hour. To calculate the new count:
...
