Answer :

By using cost-benefit analysis a local government would decide to build a new bridge if the cost incurred on construction is less than the benefits that would be derived from it.

Given that the local government has to decide to build a new bridge.

We are required to find the condition in which the government would build the bridge after using cost-benefit analysis.

A cost-benefit analysis means the process of comparing the projected or estimated costs and benefits associated with a project decision to determine whether it makes sense from a business perspective.

The government will decide to build the new bridge only if there would be some profits and we know that profit is the difference between the benefits derived and the total expenses or cost.

So, the local government will decide to build the new bridge only if the benefits derived from the new bridge would be greater than the cost incurred in construction of the new bridge.

Hence by using cost-benefit analysis a local government would decide to build a new bridge if the cost incurred on construction is less than the benefits that would be derived from it.
