The four-firm ratio is the concentration ratio between the total sales accumulated by the four largest industrial firms to the total sales of all firms present in an industry. This translates to the mathematical expression of
four-firm ratio = (total sales of four largest firms / total sales)
Since, we are given that all 10 firms have the same sales, we let the sales be equal to x.
total sales of four largest firms = 4x
total sales = 10x
The ratio is then,
four-firm ratio = 4/10
Converting this to percentage will yield us an answer of 40%.
Answer:
The private savings as a share of the GDP must have declined.
Explanation:
according to the twin deficit hypothesis:
budget deficit = savings + trade deficit - investments
the government deficit as a share of GDP declined and investment as a share of GDP remained constant that means that the savings should decline.
Answer:
Monopolistic
Explanation:
The type of competition that occurs in a competitive market without identical producers is a monopolistic one.
Using the formula for compound interest:
The formula for annual compound interest, including principal sum, is:
A = P (1 + r/n)ⁿˣ
Where:
A = the future value = $95000
P = the principal investment amount = ?
r = the annual interest rate = 0.06
n = the number of times that interest is compounded per year = 2
x = the number of years the money is invested = 0.5
95,000 = P (1 + 0.06/2)¹
95,000 = P (1.06/2)
95,000 = P (0.53)
P = 95,000 ÷ 0.53
P = 95,000 ÷ 0.53
P = 179,245.30
Total compounded interest = 179,245.30 - 95,000
Total compounded interest = 84,245
