An agricultural processing plant produces three joint products: Wheat, Corn, and Soy. The joint costs incurred for the production of these products amount to $300,000. The following information is available:

• Sales value at split-off point:
  • Wheat: $150,000
  • Corn: $90,000
  • Soy: $60,000
• Units produced:
  • Wheat: 10,000 units
  • Corn: 8,000 units
  • Soy: 5,000 units

a. Calculate the joint cost allocation using the sales value at split-off point method. b. Determine the joint cost allocation using the physical units method. c. Evaluate the suitability of each allocation method for decision-making purposes.
