Aubergine is a manufacturer of contemporary cases for tablets. The business uses a perpetual inventory system and has a highly labour-intensive production process, so it applies manufacturing overhead based on direct labour hours. Any overhead variance is deemed to be immaterial and therefore closed out to Cost of Goods Sold. Aubergine’s pre-determined overhead application rate for 2024 was computed from the following data:                                  Total estimated factory overheads     $4,200,000                                 Total estimated direct labour hours            35,000 During the first month of 2024, the business recorded the following transactions. Purchased $500,000 worth of materials on account. Separately, Aubergine paid a $3,540 bill for freight in.
