Answer:
A. 72
Explanation:
This can be calculated as follows:
Maintenance margin - Initial margin = $3,000 - $4,000 = $1,000 loss
Based on the above, we can have the following equation:
1,000 = 50,000 (b - 0.7) ........................... (1)
Where b is the futures price per unit above which there will be a margin call.
Solving equation (1) and making b the subject of the formula, we have:
b - 0.7 = 1,000/50,000
b - 0.7 = 0.02
b = 0.02 + 0.7 = 0.72
Multiply by 100, we have:
b = 0.72 × 100 = $72
Therefore, the futures price per unit above which there will be a margin call is $72.
