Answer:
The percentage decrease in utilization is 83.33%
Explanation:
According to the data, we have the following:
Coefficient of variance, m = 3
Arrival rate, ra = 45 per hour
Service rate, re = 18 per hour per lane
Therefore, in order to calculate the percentage decrease in utilization when one more checkout lane is added to the system, we have to use the following formula:
So, percentage decrease in utilization = ra / (m.re)
= 45 / (3*18) = 0.833
The percentage decrease in utilization is 83.33%
Answer:
$29 per stock

Market Value of the firm=$20,000,000*60%/10%=$120,000,000
Stock price for all shares=$120,000,000*60%=$72,000,000
Stock price per share=$72,000,000/2,500,000=$29 per share
