Final answer:
Michael should expect approximately 85 users after the first month.
Step-by-step explanation:
To find the number of users Michael should expect after the first month, we can substitute the value of x as 1 (since it is one month) into the given equation: Y = 82(1.045)^x.
Substituting x = 1, we have Y = 82(1.045)^1 = 85.49.
Therefore, Michael should expect approximately 85 users after the first month.
