Answer:
1. 20 units
2. $600
Explanation:
1. 
MC = 4q
Price, P = $80
For maximizing profits,
Marginal cost = Price of the commodity
4q = 80
q = 20 units


= 200 + 800
= 1,000
2. Profit = Total revenue - Total cost
= (Price × Quantity) - TC
= (80 × 20) - $1,000
= $1,600 - $1,000
= $600
3. We know that the firm in the short run will be produce at a point where total revenue is greater than the total variable cost
Average variable cost = variable cost ÷ quantity

= 2Q
MC = 4Q
Here, MC is greater than AVC at any given point.
so in the short run firm will producing short run positive profit.
The prices become higher when a desirable item is auctioned because the demand of the item rises when more people want it and only one person can get it. When this happens the price will rise immensely because the buyer wants it more than the other people so they bid higher to win the auction.
The equilibrium price would decrease, and the effect on equilibrium quantity would be ambiguous.
Explanation:
If demand falls and supply declines, the quantity of balance may decline, and the price of balance can increase, decline, or stay the same. If demand declines and output stays the same, the quantity of balance declines and the price of balance decreases.
Decreased demand and decreased production could contribute to a decrease in the price of balance, but the impact on the quantity of balance can not be calculated.
Consumers often put a lower premium on the product for every amount, so suppliers are able to tolerate a lower demand; thus, the output should decline.
Answer:
D
Explanation:
Focus strategy is said to be pursued when a company recognizes a relatively narrow market segment or a particular buyer group where competition is weakest and then tailored its production and product offerings towards this niche in order to serve the particular target or niche extremely well with the aim of earning a huge return on investment.
