Remember, for this question it must meet the goal Group of answer choices $2-$ Well it doesn't meet the goal, but it's very close. Uhg! This is not the answer, but it makes sense! $3-$ It meets the goal. The wait time is well under $1$ minute. But it is expensive. $1-$ Well it doesn't meet the goal, but it's cheap. And who the hell cares about customers. Make them wait!!! It would actually take more that $3$ servers to meet the $90\%$ goal. $2-$ Its meets the goal of $90\%$ and it is fairly cheapcheap. $1-$ It meets the goal and it is extremely cheap.
