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:
Variable cost per unit= $1.16 per mile
Explanation:
Giving the following information:
January 16,200 $22,650
February 17000 $23,250
March 18400 $25,450
Apri 16500 $22,875
May 17400 $23,550
June 15300 $21,850
<u>To calculate the variable cost per mile under the high-low method, we need to use the following formula:</u>
Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)
Variable cost per unit= (25,450 - 21,850) / (18,400 - 15,300)
Variable cost per unit= $1.16 per mile
