a$)$ For the existing layout, the cumulative "load $$ distance" or "movement $cos{t}^n=93,300$ feet $($enter your response as a whole number$).$

Based on the flows shown in the matrix, one should expect that the centers A and will be next to each other as they have the highest number of moves between each other. located between them is:
