Answer:
Inflation
Explanation:
Inflation refers to a situation of a general increase in the prices of goods and services in the economy. As prices of goods and services rise, the cost of living goes up. Inflation results in the purchasing power of currency to diminish.
Economist uses the consumer prices index to determine the rate of inflation. Inflation means a basket of goods and services will cost more today than it did in the prior period. Rapid economic growth that results in too much money in circulation causes inflation.
The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
If a monopolist is producing a quantity where marginal revenue is equal to $32 and the marginal cost is equal to $30, the monopolist should increase production and lower the price to maximize profits decrease production and increase the price to maximize profits.

Answer:
The closest answer is option A,$7649
Explanation:
The net present value of the investment is the present value of annual cost savings minus the initial cost of investment.
present of cash flow=cash flow/(1+r)^n
r is the discount rate of 12%
n is the year the cash flow relates to ,for instance year zero for the initial investment
NPV=-$54,000+$16,000/(1+12%)^1+$16,000/(1+12%)^2+$16,000/(1+12%)^3+$16,000/(1+12%)^4+($16,000+$7,000)/(1+12%)^5=$ 7,648.41
note that the project gives $7,000 in salvage value in year 5
To destory monopolies that were using their power to harm society.
