Particulars Dep 1 Dep 2 Total
Manufacturing overhead cost 1,360,000 3,560,000 4,920,000
Direct labour hours 553,000 803,000 1,356,000
Plant-wide overhead rate = Total manufacturing overhead / Total direct labour rate
Plant-wide overhead rate = $4,920,000 / 1,356,000
Plant-wide overhead rate = $3,628
Therefore, the Plant-wide overhead rate is $3,628 per direct labour hour.
