Then, the A material: the total cost = 32,000 (purchase price) + 1,200 (purchase cost) = 33,200 ; unit cost = 33200/2000=16.6;
Material B: total cost = 8000 (buying price) + 600 (purchasing cost) = 8600; unit cost = 8600/1000=8.6;
Material C: total cost = 50000 (buying price) + 1500 (purchasing cost) = 51500; unit cost = 51500/2500=20.6;
