Tony Little Fitness is an exercise equipment company that sells its products on late night infomercials.  To gear up for a new late night television campaign, Tony obtains a line of credit from Shady Bank, Inc. secured by a properly perfected security interest in Tony's inventory of exercise equipment. As of August 1, Tony has borrowed $300,000 and has inventory worth $180,000. However on November 1, Tony is facing some nasty personal bills and is forced to file for bankruptcy. As of November 1, Tony's balance with Shady Bank is $200,000 and the inventory is worth $250,000. Which statement is correct?

1. The trustee cannot avoid Shady Bank's security interest to any extent, because Tony borrowed more than his inventory was worth 90 days prior to bankruptcy

2. The trustee can avoid Shady Bank's security interest in $50,000 worth of the inventory.

3. The trustee can avoid Shady Bank's security interest in $70,000 worth of the inventory.

4. The trustee can avoid Shady Bank's security interest in $170,000 worth of the inventory.
