I have a word problem about exponential growth. The problem is...

"At 6am a few bacteria fall into a can of syrup in a broken garbage bag. The conditions of warmth, moisture, and food are perfect for growth and the population doubles every 20 minutes. By 6pm the bacteria are overcrowded and dry and their food is gone."

Q.At what time does the syrup become half full?
Q.A few bacteria search for more food and space. They find three more syrup cans how much of a time reprieve are they given by this find? When will the new cans be depleated?

*I feel like I need the number of the bacteria that fell into the can to be able to answer these questions. Am I over thinking this!?*
