1).
Tabule form
Price:-450 ,500
Weekly sales:- 800, 600
Ai
% change in demand= (800-600)*100
-------------
800
=200/800*100%
=25%
%change in price=500-450*100%
------------
450
=50/450*100%
=11.11%
% elasiticy of demand =%change in demand /% change in price
=25%/11.11%
=2.25%
2a)
Qd = 30 - P
Qs = 15 + 2 P
Demand and Supply schedule for the market :
Please tabulate
Price ( $ ) : 2 ,4 ,7
Qd : 28 ,26 ,23
Qs : 19 , 23 , 29
Qd = 30 - P when P = 2
Qd = 30 - 2 = 28
Qd = 30 - P when P = 4
Qd = 30 - 4 = 26
Qd = 30 - P when P = 7
Qd = 30 - 7 = 23
tabulate again
supply schedule
Please tabulate
Price ( $ ) : 2 ,4 ,7
Qd : 28 ,26 ,23
Qs : 19 , 23 , 29
Qs = 15 + 2 P when P = 2
Qs = 15 + 2 ( 2 )
= 15 + 4 = 19
Qs = 15 + 2 P when P = 4
Qs = 15 + 2 ( 4 )
= 15 + 8 = 23
Qs = 15 + 2 P when P = 7
Qs = 15 + 2 ( 7 )
= 15 + 14 = 29
2bi)
Equilibrium quantity
Qd = 30 - P
Qd = 30 - 5
Qd = 25
2bii)
At P =$ 3
Qd =30 - p
Qd =30 - 3
Qs =15 + 2 p
= 15 + 2 ( 3 )
= 15 + 6
= 21 apples
excess demand = 27 -21
= 6 apples
2ci)
Tabulate
Qd =40 - p
Price ( $ ) : 2 ,4 ,7
Qd : 38 ,36 ,33
2cii)
i ) it represent an increase in demand
2ciii)
i ) the two schedules show that there is a corresponding increase in demand for apples for ten ( 10 ) at each price
3a) Land:
It refers to all natural resources which are free gifts of nature. Land, therefore, includes all gifts of nature available to mankind—both on the surface and under the surface
3b).
i ) Land is a Primary Factor of Production

-Currency Strength
The value of the U.S. dollar compared to other foreign currencies such as the yuan, yen and the pound is important even for companies that do not import or export goods. Consumers have a choice to purchase goods or services originating in the United States or in other countries. If the U.S. dollar strengthens, companies in the industry that purchase inputs from other countries are able to be more competitive in pricing. In industries that are heavily reliant on foreign raw materials and processing, such as the clothing industry, the entire sector can be lifted or depressed with a strengthening or weakening of the dollar.
-Government Intervention
Many industries are regulated by the government in one form or another. Government agencies such as the --Environmental Protection Agency, the Food & Drug Administration or the U.S. Department of Agriculture maintain standards that all operators in an industry must follow for the safety of consumers, employees, or natural resources. Some industries are more heavily regulated than others and new laws and rules can shake up an entire industry and depress growth. For example, new child toy safety laws implemented under the Consumer Product Safety Improvement Act in 2009 threatened to wipe out many small toy producers as the requirements to test and certify the toys were cost-prohibitive to all but large toy manufacturers. Proposed changes to the Act may help alleviate the burden on small manufacturers and resellers.
-Environmental Impact
Economic growth in an industry can be impacted not only by the environmental effect the products or services have but also by consumers' perceptions of that impact. For example, the market for fur apparel declined drastically over the course of a few years in the 1990s when consumers perceived that raising and killing small animals for their fur was both inhumane and a poor use of land. Although the industry is once again picking up with international demand, the number of fur farmers in the country has substantially declined. If the public views an industry's products or services as being harmful or unsafe, most companies within the sector can experience a marked decline in sales quickly.
-Overall Economic Health
The economic state of the country
confidence can also spur growth and development or harm it. In recessionary times, consumers begin limiting their purchases to the essentials, foregoing luxury or big-ticket items. Companies also scale back production, hiring and the development of new products and services to ensure that their finances can weather the storm. In periods of overall economic growth, these companies once again expand.
