Answer:
Instructios are listed below
Step-by-step explanation:
Giving the following information:
Assume Pinkie started the year with 100 containers of ink (average cost of $ 9.10 each, FIFO cost of $ 8.60 each, LIFO cost of $ 8.00 each).
During the year, the company purchased 800 containers of ink at $10.00 and sold 600 units for $21.75 each. Pinkie paid operating expenses throughout the year, a total of $ 5,000.
FIFO:
Sales= 600*21.75= 13,050
COGS= (100*8.60 + 500*10)= 5860
Gross profit= 7190
Operating expense= 5000
Net operating profit= $2,190
LIFO:
Sales= 13,050
COGS= (600*10)= 6000
Gross profit= 7,050
Operating expense= 5000
Net operating profit= $2,050
Average-cost
Sales= 13,050
COGS= [(9.10+10)/2]*600= 5730
Gross profit= 7,320
Operating expense= 5000
Net operating profit= $2,320
