to work out how many years it takes to exceed a value would it be possible to just sub in numbers into t until it exceeds the amount?

Would you not round down, for the number of unicorns?

The ans came out as 271.828... unicorns. However if we treat unicorns like people we can say that 271.828.. unicorns exist, but we cannot have .828... of a person so we round down as another whole person does not exist yet.
