Answer:
gross profit = $3655
Explanation:
solution
by using the LIFO
cost of goods and sold includes last inventory purchases
that is new inventory
so
sales revenue = 100 units × $80
sales revenue = $8000
cost of goods sold = ( 45 units × $44 ) + ( ( 100 - 45 ) units × $43 )
cost of goods sold = 1980 + 2365 = $4345
and
gross profit is here
gross profit = sales revenue - cost of good sold
gross profit = $8000 - $4345
gross profit = $3655
