I do not understand how they got the answers to the following questions. I tried the formulas provided but my totals did not equal the answer given, and I am not sure why. Could you please explain or break the answer down for me further so I know where I am going wrong:

1. Landmark Coal operates a mine. During July, the company obtained 500 tons of ore, which yielded 250 pounds of gold and 63,400 pounds of copper. The joint cost related to the operation was $500,000. Gold sells for $325 per ounce and copper sells for $0.85 per pound.Allocate the joint costs using relative weight. With these costs, what is the profit or loss associated with Copper?

Answer:

(-444,146.14)

Weight of the Copper * Selling Price = $Revenue

Minus

Percentage which is Copper/Total Weight x Joint Costs = Cost

Revenue - Cost = Profit or Loss

3. Motorcade Company has three service departments (S1, S2, and S3) and two production departments (P1 and P2). The following data relate to Motorcade's allocation of service department costs:

Budgeted Costs Nbr of Employees

S1 $3,240,00 75

S2 $2,400,000 50

S3 $1,000,000 25

P1 150

P2 225

Service department costs are allocated by the direct method. The number of employees is used as the allocation base for all service department costs

Calculate the total service department cost allocated to production department P1

Answer:

(2,656,000.00)

Service Dept Cost S1 * (150/(150+225)) + Service Dept Cost S2 * (150/(150+225))+ Service Dept S3 *(150/(150+225))
