Answer: b. $14,000
Step-by-step explanation:
Taxes are 30%. If the LIFO amount will result in $900 more being paid in taxes then that means that $900 is 30% of the increase in income from LIFO.
Increase is therefore;
900 = x * 30%
x = 900/30%
x = $3,000
Income before tax using LIFO;
= FIFO income + increase in income
= 11,000 + 3,000
= $14,000
