Final answer:
According to the calculation, the number of 'AAs' needed is approximately 101 workers based on the given shift length, PPH goal, and volume, which does not match any of the options listed. There might be an error in the provided question.
Step-by-step explanation:
The student's question is about determining the number of 'AAs' needed to operate based on a 5-hour shift, a PPH (Pieces Per Hour) goal of 90, and a total volume of 45,379 pieces to be processed. To solve this, we calculate the total number of pieces per worker over the 5-hour shift (90 pieces per hour × 5 hours = 450 pieces per worker) and then divide the total volume by the number of pieces each worker can handle (45,379 pieces / 450 pieces per worker).
Doing this calculation: 45,379 / 450 ≈ 101 workers. Since this number is not one of the available answer choices, there seems to be an error in the question as presented. However, based on standard problem-solving techniques and the provided values, one would typically round up to the next whole number for practical application, since you can't have a fraction of a worker.
