Bismite Corporation purchases trees from Cheney lumber and processes them up to the split-off point where two products (paper and pencil casings) emerge from the process. The products are then sold to an independent company that markets and distributes them to retail outlets. The following information was collected for the month of October: Trees processed: 350 trees Production: Sales: paper pencil casings 150,000 paper pencil casings 150,000 sheets 144,000 at $0.20 per page 145,500 at $0.23 per casing The cost of purchasing 350 trees and processing them up to the split-off point to yield 150,000 sheets of paper and 150,000 pencil casings is $12,500. Bismite's accounting department reported no beginning inventory. What are the paper's and the pencil's approximate weighted cost proportions using the sales value at split-off method, respectively?
