Answer: 12400
Explanation:
It should be noted that 50% of the stick value will be paid by the customer and also 100% of the mutual fund shares value will also be paid because they are nonmarginable securities.
Therefore, 50% of $12,000 = $6,000
Total payment required will now be:
= $6,000 + $2,400 + $4,000
= $12,400.
