Determine the inventory cost using the (a) first-in, first-out (FIFO) method; (b) last-in, first-out (LIFO) method; and (c) weighted average cost method.

Instructions are listed below.

Explanation:

Giving the following information:

Jan. 1: Inventory 40 units at $165

Aug. 13: Purchase 200 units at $180

Nov. 30: Purchase 60 units at $200

Available for sale 300 units

There are 75 Units of the item in the physical inventory on December 31.

1) FIFO (first-in, first-out)

The cost of ending inventory is the cost of the last units bought.

Ending inventory= 60*200 + 15*180= $14,700

2) LIFO (last-in, first-out)

The cost of the ending inventory is the cost of the first units bought.

Ending inventory= 40*165 + 35*180= $12,900

3) Weighted-average:

Weighted average price= (165 + 180 + 200)/3= 181.67

Ending inventory= 181.67*75= $13,625.25

answer: a. the kind of population living in your neighbourhood.

the census explorer data tool by the us census bureau allows the user to zoom in on any neighbourhood within the united states and find the kind of people residing in that by race and age.  

the tool needs to needs to be used twice – once in order to find what type of people reside in a neighbourhood, and then to see the age groups of the people in the same neighbourhood.
