The population of a culture of a bacteria is tripling each day. predict how large the culture will be at the beginning of day 6 if it measures 40 units at the beginning of day 1.

9720 units

Step-by-step explanation:

There are multiple ways to find the answer to this problem, but the most logical way to find the answer if you don't know the equation is to simply take the original measurement, which is 40 units and multiply it by 3 until you reach day 6.

Below I have put the measurements for each day up to day 6.

day 1: 40 units

day 2: 120 units

day 3: 360 units

day 4: 1080 units

day 5: 3240 units

day 6: 9720 units

So, if the population of the culture of a bacteria is tripling each day and the culture measures 40 units at the beginning of day 1, then the culture will be 9720 units at the beginning of day 6.

If the time of day was confusing when solving this problem, technically it could be ignored since the time of day was consistent on both days.
