Waterfront Corporation has two producing department and two service departments labelled P1, P2, S1, S2 respectively. Direct costs for each department and the proportion of service costs used by various departments are as follows:

Cost Center	Direct Costs	Proportion of services used by:
		S1	S2	P1	P2
P1	$100,000
P2	$50,000
S1	$15,000	-	60%	30%	10%
S2	$25,000	10%	-	50%	40%

In calculating predetermined overhead rates, machine hours are used as the base in P1 and direct labor hours as the base in P2.

P1 P2

Machine hours: $50,000 $40,000

Direct labor hours: $40,000 $20,000
