Bassanio comes clean about his financial status (ll.250-271). What effect does that have on Portia?

Portia asks what amount of money Antonio owes to Shylock, and then orders Bassanio to return to Venice and offer Shylock six thousand ducats to destroy the contract. She informs Bassanio and Graziano that she and Nerissa will live like widows in their absence. They all agree to get married first and then go straight to Venice to rescue Antonio.
