A market economy can be defined as the economy of a country where by the government has a minimal influence or intervention on how the market operates.
A market economy is regulated by the individuals that owns the businesses in that economy. These individuals have the ability to direct resources that they need from production to their firms and businesses.
A market economy is largely or greatly influenced and regulated by the rate of supply and demand. Consumers in a market economy have to sometimes paid a high price for the goods and services that they require. Consumers make financial decisions in a market economy by making their choices based on self interests.

In a market economy, businesses and firms tend to have an increased of a very high rate of efficiency when producing goods and services such that they minimise or lower the cost of production while ensuring that they make high or huge amounts of profits.
Answer: (a) $197,500
(b) $ 189,500
Explanation:
Given : The marginal cost function : 
To find the cost function, we need to integrate the above function with respect to x.
Now, the additional cost incurred in dollars when production is increased from 100 units to 150 units will be:-
![\int^{150}_{100}\ C'(x)\ dx\\\\=\int^{150}_{100} (4000-0.4x)\ dx\\\\=[4000x-\dfrac{0.4x^2}{2}]^{150}_{100}\\\\=[4000(150)-\dfrac{0.4(150)^2}{2}-4000(100)+\dfrac{0.4(100)^2}{2}]\\\\=[600000-4500-400000+2000]\\\\=197500](https://tex.z-dn.net/?f=%5Cint%5E%7B150%7D_%7B100%7D%5C%20C%27%28x%29%5C%20dx%5C%5C%5C%5C%3D%5Cint%5E%7B150%7D_%7B100%7D%20%284000-0.4x%29%5C%20dx%5C%5C%5C%5C%3D%5B4000x-%5Cdfrac%7B0.4x%5E2%7D%7B2%7D%5D%5E%7B150%7D_%7B100%7D%5C%5C%5C%5C%3D%5B4000%28150%29-%5Cdfrac%7B0.4%28150%29%5E2%7D%7B2%7D-4000%28100%29%2B%5Cdfrac%7B0.4%28100%29%5E2%7D%7B2%7D%5D%5C%5C%5C%5C%3D%5B600000-4500-400000%2B2000%5D%5C%5C%5C%5C%3D197500)
Hence, the additional cost incurred in dollars when production is increased from 100 units to 150 units= $197,500
Similarly, the additional cost incurred in dollars when production is increased from 500 units to 550 units :-
![\int^{550}_{500}\ C'(x)\ dx\\\\=\int^{550}_{500} (4000-0.4x)\ dx\\\\=[4000x-\dfrac{0.4x^2}{2}]^{550}_{500}\\\\=[4000(550)-\dfrac{0.4(550)^2}{2}-4000(500)+\dfrac{0.4(500)^2}{2}]\\\\=[2200000-60500-2000000+50000]\\\\=189,500](https://tex.z-dn.net/?f=%5Cint%5E%7B550%7D_%7B500%7D%5C%20C%27%28x%29%5C%20dx%5C%5C%5C%5C%3D%5Cint%5E%7B550%7D_%7B500%7D%20%284000-0.4x%29%5C%20dx%5C%5C%5C%5C%3D%5B4000x-%5Cdfrac%7B0.4x%5E2%7D%7B2%7D%5D%5E%7B550%7D_%7B500%7D%5C%5C%5C%5C%3D%5B4000%28550%29-%5Cdfrac%7B0.4%28550%29%5E2%7D%7B2%7D-4000%28500%29%2B%5Cdfrac%7B0.4%28500%29%5E2%7D%7B2%7D%5D%5C%5C%5C%5C%3D%5B2200000-60500-2000000%2B50000%5D%5C%5C%5C%5C%3D189%2C500)
Hence, the additional cost incurred in dollars when production is increased from 500 units to 550 units = $ 189,500
Some of the social factors that have led to unemployment in South Africa amongst the youth are:
- High population growth.
- High poverty rates.
As a result of high population growth, the number of youth in South Africa has increased to a point where getting jobs for all of them is quite difficult.
High poverty rates also mean that a lot of the youth are unable to afford a tertiary education which means that they are unable to get the qualifications needed for a job.

Answer:
No, there is no contract between the two parties because of withdrawal of offer (Revocation) before the acceptance of the other party.
Explanation:
When one party offers another party and after some time the offer maker withdraws the offer by communicating that they had revoked then the offer is no more available to the other party and is often termed as Revocation. So when the offer maker revokes before the acceptance of the offer by the other party then their is no offer at consideration to the other party, which means if there is no offer then their can not be an acceptance of an offer and of course when there is no acceptance then there is no contract.
The communication of revocation was held before the acceptance of the offer of the other party which agains says that the contract was not actually formed.
