Simmy is a privately owned profit seeking hospital that specialises in operations to replace hip and knee joints. Simmy traditionally determines its prices by adding a 10% mark-up to the budgeted full cost of an operation. The fixed overheads are absorbed on the basis of operating hours using a predetermined rate.
