Snake river sawmill manufactures two lumber products from a joint milling process. the two products developed are mine support braces (msb) and unseasoned commercial building lumber (cbl). a standard production run incurs joint costs of $460,000 and results in 76,000 units of msb and 106,000 units of cbl. each msb sells for $2, and each unit of cbl sells for $10.

problem 17-27 part 3

assume the commercial building lumber is not marketable at split-off but must be further planed and sized at a cost of $543,400 per production run. during this process, 11,600 units are unavoidably lost; these spoiled units have no value. the remaining units of commercial building lumber are saleable at $10.00 per unit. the mine support braces, although saleable immediately at the split-off point, are coated with a tarlike preservative that costs $260,000 per production run. the braces are then sold for $13.00 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 final answer to 2 decimal places.)
