Remember, for this question it must meet the goal O 1 - Well it doesn't meet the goal, but it's cheap. And who the hell cares about customers. Make them wait!!! 01 - It meets the goal and it is extremely cheap O 2 - Well it doesn't meet the goal, but it's very close. Ung! This is not the answer, but it makes sense! O 3 - It meets the goal. The wait time is well under 1 minute. But it is expensive. O It would actually take more that 3 servers to meet the 90% goal. O 2 - Its meets the goal of 90% and it is fairly cheapcheap.
