The cost of underestimating the demand is considered a revenue loss that arises due to cancellation of flight costing $134. Hence, cost of underetimating the demand is

.
The cost of overestimating the demand is known as rewards. For example, free round trip ticket worth $263. Hence, the cost of overestimating the demand is

.

The z-score that yields a p-value of 0.3375 is -0.4193.
Thus, super discount airlines should overbook the flight by 35 + (-0.4193 x 24) = 35 - 10.0632 = 24.9368 = 25 seats.
Therefore, super discount airlines should overbook the flight by 25 seats.
Answer:
Total dividend paid = $340,000
Preferred dividend = 7% x $4 x 150,000 x 3 years = $126,000
Dividend paid to common stock holders
= $340,000 - $126,000
= $214,000
The correct answer is C
Explanation:
There is need to calculate the preferred dividend for 3 years, which is a function of dividend rate, current market price, number of preferred stocks outstanding and number of years. The current market price of the preferred stock is used for the computation because the preferred stock has no par value. Then, the amount of dividend paid to common stock holders is the difference between the total dividend paid and preferred dividend.
