Answer to question 1

Answer to question 2

1) average cost per unit (rounded) for May –

(600*2.8)+(700*3)+(900*3.1)+(500*3.2)/(600+700+900+500) = 3.03

2) amount of cost of goods sold assuming the LIFO cost flow method –

(500*3.2)+(900*3.1)+(700*3) = 6490

3) amount of gross margin assuming the weighted-average inventory cost flow method –

(2100*4.7)-(2100*3.03) = 3507

4) amount of gross margin assuming the FIFO cost flow method –

(2100*4.7) – (600*2.8)+(700*3)+(800*3.1) = 3610

Answer to question 3

Solution 1:

Weighted average cost per unit = [(100*$4) + (300*$4.40)+ (500*$4.60) + (100*$4.80)] / (100+300+500+100)

= $4.50

Hence option B is correct.

Solution 2:

Ending inventory using FIFO method consist of 100 unit of third purchase = 100*$4.80 = $480

Hence option A is correct.

Solution 3:

Gross margin = Sales – COGS = (900*$7.80) – ($4,500 – $480) = $3,000

Hence option C is correct.
