Answer:
a. increase price in the short run but not in the long run.
Explanation:
A perfectly competitive market is one in which firms in an economy produce similar goods, and use resources that are limited in quantity.
An increase in demand will result in a corresponding increase in price, and results in firms making high profits. In the diagram below it results in a shift of demand from D1 to D2.
In the long run as firms have low barrier to entry more firms enter the market and supply shifts from S1 to S2. There is reduction in prices and profits start to fall. This is illustrated in the second diagram.
 
        
             
        
        
        
The demand curve for a perfectly competitive firm is completely elastic and a horizontal line. Monopolistically competitive demand curve is downward sloping and is more elastic than monopoly because there are more substitutes.

Answer:
Interest= $26,131.91
Explanation:
Giving the following information: 
Annual deposit= $2,000
Number of periods= 20 years
Interest rate= 5%
<u>First, we need to calculate the future value using the following formula:</u>
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {2,000*[(1.05^20) - 1]} / 0.05
FV= $66,131.91
<u>Now, we can determine the interest earned:</u>
Interest= future value - total investment
Interest= 66,131.91 - 20*2,000
Interest= $26,131.91
