Answer:
gross profit under FIFO = $40,570 - $25,220 = $15,350
gross profit under LIFO = $40,570 - $26,340 = $14,230
gross profit under weighted average = $40,570 - $26,240 = $14,330
gross profit under specific id. = $40,570 - $26,070 = $14,500
Explanation:
sales revenue = (290 x $86.60) + (160 x $96.60) = $40,570
COGS under FIFO:
130 x $51.60 = $6,708
160 x $56.60 = $9,056
80 x $56.60 = $4,528
80 x $61,60 = $4,928
total COGS = $25,220
COGS under LIFO:
240 x $56.60 = $13,584
50 x $51.60 = $2,580
160 x $63.60 = $10,176
total COGS = $26,340
COGS under weighted average:
weighted average = [(130 x $51.60) + (240 x $56.60) + (100 x $61.60) + (180 x $63.60)] / 650 = $58.31
450 x $58.31 = $26,239.50 ≈ $26,240
COGS under specific method:
80 x $51.60 = $4,128
210 x $56.60 = $11,886
60 x $61.60 = $3,696
100 x $63,60 = $6,360
total COGS = $26,070
