What you can do is start with the key details in it... the main ones are that the bacteria grows every 30 minutes, you start with 1 bacteria, and the end time is 180 minutes. Basically you know that 3 goes into 18 6 times so 30 goes into 180 6 times which means that if you started with 1 bacteria you will end up with 7. Understand?
