Answer:
$3,000
Step-by-step explanation:
Units Cost/unit
2/1/20 Purchase 52 $47
3/14/20 Purchase 90 $50
5/1/20 Purchase 70 $52
157 units were sold at $70 per unit
tax rate = 20%
FIFO method calculates COGS using the price of the last units purchased.
COGS using last in, first out (LIFO) = (70 x $52) + (87 x $50) = $3,640 + $4,350 = $7,990
gross profit = total sales revenue - COGS = (157 x $70) - $7,990 = $10,990 - $7,990 = $3,000
