A company runs two production cost centres M1 and M2, and two service cost centres S1 and S2. The total allocated and apportioned overheads for each are as follows:

M1	M2	S1	S2
30,000	35,000	10,000	15,000

It has been estimated that each service cost centre does work for other cost centres in the following proportions:

	M1	M2	S1	S2
% of service cost centre S1 to:	55%	45%	-	-
% of service cost centre S2 to:	40%	45%	15%	-

Calculate the total overheads for production cost centre M1 after the reapportionment of service cost centre costs have been carried out.
