Answer: b) Loss of $7,500,000.
Step-by-step explanation:
The total the investment bank paid when underwriting was:
= 10.50 * 10,000,000 shares
= $105,000,000
The total they then sell to the public is:
= 9.75 * 10,000,000
= $97,500,000
The profit is:
= Selling revenue from public - Buying cost from company
= 97,500,000 - 105,000,000
= -$7,500,000
