Date units purchased cost per unit
january 1 10 $8.00 (beginning inventory)
january 18 50 $9.00
february 20 20 $11.00
march 15 10 $12.00 (ending inventory: 19)

the specific identification method indicates the following units to be on hand: january 1, (2); january 18, (5); february 20, (6); march 15, (6). the cost of goods sold is

Cost of Goods sold= $ 671

Step-by-step explanation:

On Jan 1 Units Purchased = 10

and Units on hand = 2

so goods sold = 10 - 2 =8

On Jan 18 Units Purchased = 50

and Units on hand = 5

so goods sold = 50 - 5 = 45

On Feb 20 Units Purchased = 20

and Units on hand = 6

so goods sold = 20 - 6 = 14

On march 15 Units Purchased = 10

and Units on hand = 6

so goods sold = 10 - 6 = 4

So, the cost of gods sold can be found by multiplying good sold on each day with its cost per unit and then adding them

cost of gods sold = goods sold on Jan 1 * Cost per unit + goods sold on Jan 18 * Cost per unit + goods sold on Feb 20 * Cost per unit +goods sold on March 15 * Cost per unit

cost of gods sold = 8*8 + 45*9 + 14*11 + 4*12

                             = 64+405+154+48

                              = 671

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

50-38=12
