Aculture started with 6000 bacteria . after 5 hours it grew 7800 bacteria. predict how many bacteria will be present after 13 hours . use the formula p = ae^kt round the nearest whole number

We know that we need to use the formula: 
where 
is final population of bacteria after  hours
is the initial population 
is the growth rate 
is the time in hours

The first thing we are going to do is find . We know for our problem that: , , and . Lets replace those values in our formula:


Now, to find  we are going to isolate , and then apply logarithms:







Now that we have , we are going to use our formula one more time, but this time :





We can conclude that the culture will have 11796 bacteria after 13 hours.
