Pump_it_up Ltd produces two models of water pumps, the household model and the commercial model. Currently, the company uses a conventional costing system i.e.. labour hours. to estimate its manufacturing overhead. The estimated production volumes are 1,000 units of household model and 500 units of commercial model in the forecasting period.
