question 31

Multiple Choice

Prior to installing a JIT system, Clark Company used machine hours to assign maintenance costs to its three products of 4-cm, 6-cm, and 9-cm insulation. The maintenance costs totalled $400,000 per year. The machine hours used by each product and the quantity produced of each product are as follows:
$\begin{array}{lcc} &\underline{\text {Machine Hours}}& \underline{\text {Quantity Produced}}\\4 \mathrm{~cm} & 12,000 & 31,250 \mathrm{rolls} \\6 \mathrm{~cm} &20,000 & 25,000 \mathrm{rolls} \\9 \mathrm{~cm} & 18,000 &12,000 \mathrm{rolls}\end{array}$ After installing JIT,three manufacturing cells were created and the cell workers were trained to perform maintenance.Maintenance costs for the three cells still totalled $400,000; however,these costs are now traceable to each cell.
$$\begin{array} { c r } \text { Cell } 4 \mathrm {~cm} & \$ 100,000 \\\text { Cell, } 6 \mathrm {~cm} & 120,000 \\\text { Cell } 9 \mathrm {~cm} & 180,000\end{array}$$
-Refer to the figure.What would be the maintenance cost per roll of 6-cm insulation before JIT is installed?

• A)$6.40
• B)$9.33
