  Solution
Units available for sale = 200
Ending inventory = 80
Units sold = 200-80 =120
FIFO
Cost of merchandise inventory = (10*116)+(70*122)=9700
Cost of merchandise sold = (50*104)+(50*112)+(20*116)=13120
LIFO
Cost of merchandise inventory = (50*104)+(30*112)=8560
Cost of merchandise sold = (70*122)+(30*116)+(20*112) = 14260
Weighted average cost
Average cost = ((50*104)+(50*112)+(30*116)+(70*122))/200= 114.10
Cost of merchandise inventory = 80*114.10 = 9128
Cost of merchandise sold = 120*114.10= 13692
