The maximum number of shares that we can buy is 301 shares.
Option C
Explanation:
margin account is the one that allows us to purchase a greater notional value of securities than the account's cash value.
Here, the margin account currently has available cash is $4700.
Maximum purchase can be calculated by dividing the margin account value divided by initial margin requirement.
Therefore, maximum purchase = $4,700/.6 = $7,833.33
Cost of one share is $26.
Maximum number of shares = $7,833.33/$26 = 301.269 which is approximately 301 shares, rounded down to the last full share.
