Answer:
The correct answer is B. The law of demand states that quantity demanded will vary inversely with the price of the good.
Explanation:
The law of demand states that the value of demand decreases as the price of the product increases, that is, between the value of demand and the price there is an inverse relationship, therefore, an increase in price causes a decrease in demand, and a decrease in price causes an increase in demand.
Therefore, manufacturers who have decided to produce more should know that an increased number of goods can only be sold at a lower price.
The quantity of goods purchased depends on the price as well as on the average income of the buyers, the size of the market, the price and usefulness of other goods, including substitutes, subjective tastes and preferences of buyers.

Solution :
At every stage the formula used will be :

After the junior year, Aunt Mabel's bank balance will be :

= $ 7,322.65
Aunt Mabel's bank balance after sophomore year will be :
7,322.65 + 1000 = $ 8,322.65

= $ 8060.677
After the freshman year, bank balance of Aunt Mable's will be :
8060.677 + 6000 = $ 14,060.677

= $ 14.0606
If Aunt Mabel can predict the interest rate with accuracy, she will have to deposit :
$ 14.0606 + $ 9000 = $ 9,014.06

= $ 8,565.241
Answer:
Cost of ending inventory is $3,550
Revised Question:
The given question is incomplete. The complete question is as follows:
A company had the following purchases and sales during its first year of operations:
Purchases Sales
January 10: 6 units at $120
February 20: 5 units at $125
May 15: 9 units at $130
September 12: 8 units at $135
November 10: 13 units at $140
On December 31, there were 26 units remaining in ending inventory. Using the Perpetual FIFO inventory valuation method, what is the cost of the ending inventory? (Assume all sales were made on the last day of the month.)
Explanation:
FIFO (First in First out) inventory system refers to the inventory system in which it is assumes that first purchases are the first sold goods. So for calculating the cost of ending inventory we'll calculate the value of unsold goods.
<em>Calculations:</em>
<h3> Unsold goods Cost of unsold goods</h3><h3> 13 (13 X $140) =$1820</h3><h3> 8 (8 X $135) =$1080</h3><h3><u> 5 (5 X $130) =$650</u></h3><h3>Total unsold goods 26 Total cost of unsold goods =$3,550 </h3>
So the cost of ending inventory is $3,550
