PeriodicAssuming the use of a periodic inventory system, prepare a summarized income statement through gross profit for the month of

January under each method of inventory: $(a)$ average cost $($round the average cost per unit to the nearest cent$),($b$)$ FIFO, $(c)$ LIFO,

and $(d)$ specific identification. For specific identification, assume that the first sale was selected from the beginning inventory and the

second sale was selected from the January $12$ purchase. Show the inventory computations in detail.

Between FIFO and LIFO, which method results in the higher pretax income? Which method results in the higher EPS?

Between FIFO and LIFO, which method results in the lower income tax expense? Explain, assuming a $20$ percent average tax rate.

Between FIFO and LIFO, which method produces the more favorable cash flow? Explain.
