Answer:
Pretax less by $ 2,000
Step-by-step explanation:
Under LIFO, Goods that were purchased last are sold first.
Opening stock: 300 @ $ 10
Additional purchases: 1000@ 20
Units sold: 1200.
Scenario one: with 1000 new purchases
=(1000x20)+ (200X10)
=$20000+2000
=$22,000.00
Scenario two: With 1200 as new purchases
=12000x20=$ 24,000
The difference= $ 24,000-$22,000= $2,000.00
Pre tax profit less by $2,000.00
