PMP Practice: Execute change management strategy according to the methodology

Ash Okonkwo is managing a warehouse automation project for Swift Ridge Labs. During month 5, the sponsor requests that three additional conveyor belt systems be added to the scope. The change control board approves the request. The original project had a budget at completion (BAC) of $850,000 and was scheduled for 10 months. At the time of the approved change, the project has spent $380,000 and completed work valued at $425,000. The approved change will add $180,000 to the budget and extend the timeline by 2 months. What is the new budget at completion (BAC) after incorporating this approved change?
