How did the attack Economy?
The boston bombing affects economy because the city has to gain enough money to pay for many of the buildings that were destroyed during the bombs. For fake legs they will need to spend more than $100,000 to pay for everybody. About $23 million for everyones doctor fees, and more than $500,000 million to fix the buildings.
This is the street that most of the buildings were bombed and burn't down that the government has to raise the money to get them back.
