Answer: The FIFO method result in lower cost of inventory than the LIFO method.
Step-by-step explanation:
In the FIFO method old inventories are used to determine cost of goods sold (COGS), which result to less income because COGS is lesser, while it is greater in LIFO.
However, in LIFO, old and outdated inventories are valued lower than the present price. It not a good indicator of ending inventory value.
B. To calculate the degree of freedom of the inventory sample given: 1. 225221, 2. 119100, 3. 100113, 4. 212200, 5. 248245.
STEP 1. Find the mean or average of the samples.
Let x be the sample average, and N the sample size which is 5
x = 225221 + 119100 + 100113 + 212200 + 248245/5 = 180975.8
STEP 2. Degree of freedom Df is given as Df = N - 1
Remember, N is the sample size given as 5.
Df = 5 - 1 = 4.
CONCLUSION:
This shows that four numbers from the samples given have the freedom to vary as long as the average remains 180975.8.
is 5(x+3y) and the best answer for LCD is 
is 2(x+3y)
