I didn’t understand why 1 is eliminated in the formula for question 121?
In question 120 formula has P(1+_r)^t
But in question 121 (number of bacteria) formula doesn’t have 1 in it, instead it has P(x)^t = 200(3)^6
I wrote it like this and it was wrong 200(1+3)^6
Can I have an explanation about the logic of (1) in the formula ?
