We know that will include terms.
But will also add 9, so we can subtract 9. Putting this into the equation, we get:
Using the trivial inequality, which states that a square of a real number must be positive, we can say that in order to have the minimum number of members, we need to make (t-3) = 0. Luckily, 3 months is in our domain, which means that the minimum amount of members is 19.
