JIT Features and Product Costing Accuracy Prior to installing a JIT system, Buckner Company, a producer of automobile parts, used maintenance hours to assign maintenance costs to its three products (wheels, rims, and ball bearings). The maintenance costs totaled $6,093,220 per year. The maintenance hours used by each product and the quantity of each product produced are as follows: After installing JIT, three manufacturing cells were created, and cell workers were trained to perform preventive maintenance and minor repairs. A full-time maintenance person was also assigned to each cell. Maintenance costs for the three cells still totaled $6,093,220; however, these costs are now traceable to each cell as follows: perform preventive maintenance and minor repairs. A full-time maintenance person was also assigned to each cell. Maintenance costs for the three cells still totaled $6,093,220; however, these costs are now traceable to each cell as follows: Required: 1. Compute the pre-JIT maintenance cost per unit for each product. If required, round your answers to the nearest cent. 2. Compute the maintenance cost per unit for each product after installing JIT. If required, round your answers to the nearest cent. \begin{tabular}{lll} Wheels & per unit \\ Rims & per unit \\ Bearings & $ & per unit \\ \hline \end{tabular}
