b

b
Y = $100,000 x 30
-0.4150
= $24,378
Total direct labour cost for first 30 batches = 30 x $24,378 = $731,340 Less: Total direct labour cost for first 10 batches = 10 x $38,459 = $384,590 Therefore total direct labour cost for these 20 batches = $346,750 The direct labour cost of each of the other 10 batches in this stage is the same as that of the thirtieth batch:
