Technicians at Coastal Radiology Queensland (CRQ) conduct X-rays, ultrasounds, computed- tomography (CT) scans and magnetic resonance imaging (MRI). The management accountant has gathered the following information in preparation for the budget for the year to 30 June 2019. The costing system that management is using at CRQ has one cost driver, technicians' remuneration, and costs are calculated per procedure. The management accountant is not sure that the system is reporting sufficiently accurate costs on which to base charges or to monitor performance.

Recommend a costing system that is capable of addressing issues raised in your evaluation. Note: apply the system that you have recommended. 4. There's no reason for me to get excited about the choice between the weighted-average and FIFO methods in my process-costing system. I have long-term contracts with my materials suppliers at fixed prices. Do you agree with this statement made by a plant controller? Explain your answer.
