. Compute the cost assigned to ending inventory using (a) FIFO, (b) LIFO, (c) weighted average, and (d) specific identification. (For specific identification, units sold consist of 600 units from beginning inventory, 300 from the February 10 purchase, 200 from the March 13 purchase, 50 from the August 21 purchase, and 250 from the September 5 purchase.)

Since the information is missing, I searched for a similar question and found the attached image. The numbers vary slightly, but you can use this exercise as an example:

cost assigned to ending inventory under:

FIFO = $108,530 - $85,045 = $23,485

LIFO = $108,530 - $85,430 = $23,100

weighted average = $108,530 - $85,697 = $22,833

specific identification = $108,530 - $85,245 = $23,285

first we should calculate COGS:

under FIFO

March 15 sales = (660 x $60) + (55 x $57) = $42,735

September 10 sales = (275 x $57) + (110 x $45) + (160 x $65) + (185 x $61) = $42,310

total = $85,045

under LIFO

March 15 sales = (110 x $45) + (330 x $57) + (275 x $60) = $40,260

September 10 sales = (570 x $61) + (160 x $65) = $45,170

total = $85,430

under weighted average

March 15 sales = 715 x ($108,530 / 1,830) = $42,404

September 10 sales = 730 x ( / 1,830) = $43,293

total = $85,697

under specific identification

For specific identification, units sold consist of 660 units from beginning inventory, 230 from the February 10 purchase, 110 from the March 13 purchase, 110 from the August 21 purchase, and 335 from the September 5 purchase.

(660 x $60) + (230 x $57) + (110 x $45) + (110 x $65) + (335 x $61) = $85,245

the page presents four different kinds of threats that volcanoes pose and what to do before, during, and after an eruption.

the assumption the narrator makes in this excerpt is that the messages he heards were going to hurt the narrator's mom; the narrator just springs in to action. the narrator doesn't specify in this excerpt why he believes that the messages present a problem that requires protection.
