Answer: Minimum efficient scale is 8 units.
Explanation:
Given that,
Cost function: C(q) = 64 + 
Marginal cost function: MC = 2q
Average cost: AC = 
= 
=

Answer:
c. There is an "opportunity cost" associated with using reinvested earnings, hence they are not "free."
Explanation:
When the reinvested earnings are invested that is basically the earnings associated with reinvestment would earn the same like that earned by the investment if not withdrawn and invested.
Let us say for example: Amount invested = $1,000
Return on such investment = $100
Now if such earnings are also reinvested then
Earnings = $110
Now if this $110 is used rather than investing again, then there is the opportunity cost of earning $11 on such reinvestment.
Thus, statement c is correct.
When a negative real shock hits the economy, without monetary intervention, both inflation and real growth will decline.
Inflation can be defined as an increase in prices, which can be translated as a decrease in purchasing power over time. The rate of decline in people's purchasing power can be reflected in the increase in the average price of a selected basket of goods and services over a period of time. An increase in price, which is often expressed as a percentage, means that one unit of currency is effectively buying less than it did in the previous period. Inflation can be contrasted with deflation, which occurs when prices fall and people's purchasing power increases.
