A more thorough explanation:

A lowest responsible bidder is a person or company who offers the lowest price for a project or job, while also meeting all the requirements and specifications of the contract. The bidder must also have a proven track record of completing similar projects successfully.

For example, if a city needs to build a new bridge, they will put out a request for bids from construction companies. The lowest responsible bidder will be the company that offers the lowest price for the project, while also having the necessary experience and resources to complete the job.

Another example could be a company looking to hire a contractor to build a new office building. The lowest responsible bidder would be the contractor who offers the lowest price for the project, while also having a history of completing similar projects on time and within budget.

These examples illustrate how the lowest responsible bidder is chosen based on both their price and their ability to complete the project successfully. It is important to choose a bidder who is financially stable and has a good track record to ensure that the project is completed on time and within budget.
