Answer:
the sum of all prices that the individual buyers are willing and able to pay for each possible quantity of the good.
Explanation:
Market demand refers to the sum of the individual demand for a commodity from all buyers in a given market.
A market demand curve is therefore a graph that shows the the sum of the individual demand for a commodity from all buyers in the market.
Therefore, the correction option is "the sum of all prices that the individual buyers are willing and able to pay for each possible quantity of the good".
Note that the market demand curve is a downward sloping curve due to the fact that there is a negative relationship between price and quantity demanded. That is, as price increases, the quantity demanded decreases. On the other hand, as price decreases, the quantity demanded increases.
Also note that an example of a market demand curve is given in the attached graph. From the graph, it can be seen that when price is 
, quantity demanded is 
. But when price falls to 
, quantity demanded increased to 
. This shows the negative relationship between price and quantity demanded as explained above.
Answer:
TRUE
Explanation:
A perfect competition is characterised by many buyers and sellers of homogeneous goods and services. Market prices are set by the forces of demand and supply. There are no barriers to entry or exit of firms into the industry.
In the long run, firms earn zero economic profit. If in the short run firms are earning economic profit, in the long run firms would enter into the industry. This would drive economic profit to zero.
Also, if in the short run, firms are earning economic loss, in the long run, firms would exit the industry until economic profit falls to zero.
In the short run, the firm would continue to operate if its revenue covers variable cost. if it doesn't it would shut down.

Explanation:
Kansas Enterprises
Formula for Depreciation expenses
Annual depreciation expense=(Cost-Residual value)/Useful Life
Where,
Cost = 72,500
Residual value =7,950
Useful life = 5 years
Let plug in the formula
=(72,500-7950)/5
=64,550/5
=$12,910/year
Therefore depreciation expense for 2021
=$12,910
Calulation for Book value
Book value = $72,500 – ($12,910× 2)
$72,500 -$25,820
=$46,680
Therefore the book value would be $46,680
During decline, sales growth becomes negative, profits decline, competition remains high, and the product ultimately reaches its ‘death’.
it is during this phase that new technologies will replace old, and dying technology and start a new product life cycle.
