问题如下：

7 Based on Exhibit 1, the opportunity cost for purchasing the 90,000 shares of BYYP is:

选项：

A.

$22,500.

B.

$60,000.

C.

$75,000.

解释：

C is correct.

Opportunity cost is based on the number of shares left unexecuted in the order and reflects the cost of not being able to execute all shares at the decision price. The opportunity cost is calculated as:
Opportunity cost = $(S-\sum S_j)(P_n-P_d)$= (120,000 – 90,000) × ($42.50 – $40.00)
= $75,000

为什么用收盘价做Pn？
