A. Calculate average-cost per unit= $5.6976

A2.. Compute the inventory at April 30 on each of the following bases. Assume that perpetual inventory records are kept in units only. (1) First-in, first-out (FIFO). (2) Last-in, first-out (LIFO). (3) Average-cost.

FIFO= $6965 LIFO=$6160 Average-cost=$6552

B. If the perpetual inventory record is kept in dollars, and costs are computed at the time of each withdrawal, what amount would be shown as ending inventory under (1) FIFO, (2) LIFO and (3) Average-cost? (Round average cost per unit to 4 decimal places, e.g. 2.7621 and final answers to 0 decimal places, e.g. 6,548.)

FIFO= ?

LIFO=?

Average-Cost=?
