1 Part 1 of 5 1.09 points ! Required information Problem 17-27 Joint Costs (LO 17-4, 17-5) [The following information applies to the questions displayed below.] 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 $340,000 and results in 64,000 units of MSB and 94,000 units of CBL. Each MSB sells for $3, and each unit of CBL sells for $8. eBook References Problem 17-27 Part 1 Required: 1. Calculate the amount of joint cost allocated to commercial building lumber (CBL) on a physical-units basis. (Round the calculation of "Relative Proportion" to the nearest whole percent. Round your final answer to the nearest dollar amount.) Joint cost allocated to CBL Problem 17-27 Part 2 2. Calculate the amount of joint cost allocated to the mine support braces (MSB) on a relative-sales value basis. (Round the calculation of "Relative Proportion" to the nearest whole percent. Round your final answer to the nearest dollar amount.) Joint cost allocated to MSB Problem 17-27 Part 3 3. Assume the commercial building lumber is not marketable at split-off but must be further planed and sized at a cost of $348,400 per production run. During this process, 10,400 units are unavoidably lost; these spoiled units have no value. The remaining units of commercial building lumber are saleable at $14 per unit. The mine support braces, although saleable immediately at the split-off point, are coated with a tarlike preservative that costs $140,000 per production run. The braces are then sold for $7.00 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.) Cost per unit of CBL Problem 17-27 Part 4 4. If Snake River Sawmill chose not to process the mine support braces beyond the split-off point, the contribution from the joint milling process would increase or decrease by what amount? The contribution of MSB would
