Final answer:
The Budget at Completion (BAC) of the project is $350,000, which is the total cost allocated for the project and does not change based on the work completed so far.
Step-by-step explanation:
To determine the Budget at Completion (BAC) for the project, we can use the information given: $350,000 is the total cost of the project, $150,000 has already been spent, and 35% of the work has been completed.
The calculation of the BAC, typically does not change once the project has begun, unless there are approved changes to the project scope or budget. The BAC, in this scenario, remains as the total cost of the project, which is $350,000.
