Answer:
$100
Explanation:
Total cost if he installs seven systems = $300
Total cost if he installs eight systems = $400
Therefore, the marginal cost of installing 8th system is the difference between the total cost of installing eight systems and the total cost of installing seven systems.
Marginal cost of installing 8th system:
= Total cost of installing 8 systems - Total cost of installing 7 systems
= $400 - $300
= $100
The profit maximization conditions says that the marginal cost must be equal to the marginal revenue.
Hence,
William will install eight systems per day only if the eight customer is willing to pay at least $100.

At a point in time when a number of small businesses are operating in this manner, the larger companies would recognize and account for their influence on the market.

When a Government increases the social security payments, this result in transfer of money from government to social security account but it does not generate any goods are services in the country.
When the stock prices increases in the country, there is more likely that the individuals will invest in the stocks. So investments will increase and thus GDP will rise.
