Can you explain number 4 if it's undercosted or overcosted? Because I know the correct answer is B but how can the work be shown? Thank you :)

The next two questions are based on the following information: Until 2022, the company is using an activity-base costing (ABC) system to allocate the company's manufacturing overhead to includes organization-sustaining costs and idle capacity costs). 3 Under the ABC system, how much of the total manufacturing overhead cost would be assigned to Product X13? B.$564,000ACTIVITYRate:B.$1,010,000(884,00052,000)=17MHsC.$784,000(210,000700)=300setupsE.Noneoftheabove(480,0002)=240,000product Now, Total MoH cost: (1200017)=204,000(400300)=120,000(1240,000)=240,000564,000 4 The company is considering switching to a traditional costing system where machine hours are used as the allocation base for manufacturing overhead cost when computing a plant-wide overhead rate. Determine by how much the Product X13 is over/undercosted relative to ABC system
