Answer:
670 shares
Step-by-step explanation:
The assumption here is that since Merk and Boeing constitutes the entire market portfolio,it is expected that the investor would invest the same dollar amount in each stock.
The amount invested in Merck is the number of shares multiplied by share price.
Merck share price is $36.70,invariably $36,700 ($36.70*1000) was invested in Merck.
Number of shares in Boeing=amount invested in Merck/Boeing share price
boeing share price=$38.223 billion/697.5 million shares=$54.8
Number of shares in Boeing=$36,700/$54.8=670 shares
