Required information [The foiiowing information appiies to the questions displayed beiotvj Snake River Sawmill manufactures two lumber products from ajoint milling process. The two products developed are mine support braces {M53} and unseasoned commercial building lumber [CBL]. A standard production run incursjoint costs of $430,000 and results in 73,000 units of M58 and 108,000 units of CBL. Each MSB sells for $4, and each unit of CBL sells for $8. 3. Assume the commercial building lumber is not marketable at splitoff but must be further planed and sized at a cost of $512,200 per production run. During this process, 11,800 units are unavoidably lost; these spoiled units have no value. The remaining units of commercial building lumber are saleable at $12 per unit. The mine support braces, although saleable immediately at the split-offpoint, are coated with a tarlike preservative that costs $280,000 per production run. The braces are then sold for $14.00 each. Using the net- realizable-value basis, compute the completed cost assigned to each unit of commercial building lumber. {Round the calculation of "Relative Proportion" to the nearest whole percent. Round your nal answer to 2 decimal places.] _:|
