I am having trouble answing a question, I have used the example that is just like the problem that I am trying to answer and when I clicked on check answer the answer was wrong. Here is the question that I am trying to answer: The following information is departmental cost allocation with two service departments and two production departments.

Percentage Service Provided to

Department Cost S$1$ S$2$ P$1$ P$2$

Service $1($S$1)$ $ $44,0000\%20\%40\%40\%$

Service $2($S$2)34,0002002060$

Production $1($P$1)240,000$

Production $2($P$2)290,000$

What is the amount of service department cost allocated to P$1$ and P$2$ using the direct method if the cost in P$1$ is changed from $$240,000$ to $$260,000?$
